I Hate Past Me

"P"

- Karkat Vantas, Homestuck

The inverse of Future Me Scares Me, where a character sees the past and either meets or somehow witnesses the actions of their past self, and just can't stand them. Maybe they were once a villain, and now that they've reformed dislike how evil they once were, or, inversely, they're more evil and show disdain for how "weak" their past self is. Maybe they're just more experienced, and are annoyed with how inexperienced and impulsive they were in the past. In any case, they're constantly ticked off by their past.

See also Future Me Scares Me, so for this from the point of view from the past self, go there. Compare Old Shame, a more mundane version of this trope, and Amnesiac Dissonance, where something similar happens as a result of previously-hidden memories being recovered. Contrast Other Me Annoys Me.

Anime

 * In Noein, Karasu condemns his past self for being an utter coward. Considering what he's trying to do, not an entirely unreasonable attitude. And then.

 * During Genis-Vell's omnipotent madman phase, he brought Rick Jones's teenage self to the present—that is, Rick from before the Gamma Bomb accident that created the Hulk, when Rick was forced to grow up and start taking responsibility for his actions. Naturally, present-day Rick can't stand him.
 * Doctor Strange's villains occasionally attempt mind-games like showing him his life as an arrogant young surgeon. He's never once been tempted to go back.

Fan Fiction

 * Asuka in Evangelion Re-Take feels somewhat vitriolic toward her past self, particularly when she enters into a romantic relationship with Shinji, whom future Asuka has much more reason to hate. There's also some self-loathing and jealousy involved.
 * In Kyon Big Damn Hero, Kyon thinks that Future!Kyon is arrogant and condescending and that Past!Kyon is incompetent. This is played with, as Kyon tells Koizumi that he mostly annoys himself so that he'll remember things that he'll have to do later, but this was played straight during a later chapter when Future!Kyon sent a text to Kyon calling him an idiot for not seeking help from Yuki during an encounter with an enemy slider.
 * In White Devil of the Moon, Nanoha, who is the reincarnation of Princess Serenity, strongly disapproves of the Princess' actions during the era of the Moon Kingdom, leading to a Calling The Old Woman Out moment against the ghost of the queen.
 * In A Sticky Situation, this is fairly true for Impmon. And for good reason and that's not even considering his canon actions.

Film
"Cohaagen: You'll like being Hauser.
 * In Back to the Future II, Old Biff doesn't particularly like Young Biff, thinking of him as an ignorant macho idiot (like his grandson), but is willing to give him the secret to infinite wealth since it will make himself rich in the future. Unfortunately, the end result is a Biff much more diabolical than either of them.
 * Young Biff didn't care much for Old Biff either, thinking he was some crazy old coot even when Old Biff showed him his plan to make him/them rich was legit. So...I Hate Future Me?
 * A non-Time Travel example in Total Recall. Quade learns that he was originally Hauser, one of Big Bad Cohaagen's agents who volunteered to have his memory erased and replaced with Quade's personality, and doesn't particularly agree when Hauser's pre-made recordings start taunting and screwing with him. When Cohaagen tries to reprogram him as Hauser:

Quade: The guy's a fucking asshole!"

"Future Doctor Smith: I never liked myself much anyway."
 * Disney's The Kid.
 * Zathura has
 * In Triangle, a woman who's been caught in a series of time loops has gone completely over the edge and when she finds herself transported to the start of the day, she sees her past self yelling angrily at her son. Her response?

Literature

 * In the Mistborn novel The Alloy of Law, Miles burning gold sees two possible "pasts" of himself, and both hate each other.
 * This is a common effect of burning gold, actually, since it shows you either your past or a possible past (it's rather unclear- gold is probably the least understood of the core allomantic metals, since burning it is often a disturbing experience). Vin, the heroine of the original Mistborn trilogy, is also extremely uncomfortable with seeing her pre-Character Development Broken Bird self while burning gold, and never does it again.
 * Upon seeing his decisions from an observer's point of view, Ebenezer Scrooge eventually has little but large amounts of disdain for the choices his past self made, occasionally berating him despite knowing he can't hear.

 * In Night Watch Sam Vimes is annoyed to realize that past him was a "twerp".
 * In Stephen Baxter's novel The Time Ships, when Moses meets his past self he initially doesn't like his trousers, his waistcoat, his attitude, or him. Damn young turk!
 * In the "Q-Continuum" series of Star Trek novels, Q takes Picard on a trip through his past to show him why breaching the galactic barrier would be a bad idea. Throughout the trip Q laments his past self's actions. Understandable, since he did grant

Live Action TV

 * In the Red Dwarf episode Time Slides, Lister goes back in time to visit his teenage self who turns out to be an authority-hating punk who believes everything is 'crypto-fascist'. Also, inverted in Out of Time.
 * In the Doctor Who story The Five Doctors, after the past Doctors return to their respective timelines, the present Doctor (the fifth one) says "I am not the man I was ... thank goodness." This implies that while he might not exactly hate his past selves, he considers them phases he's since outgrown.
 * This is a recurring theme in multi-Doctor stories, which inevitably end up with the various incarnations of the Doctor bickering with each other, such as the Third and Second Doctors in "The Three Doctors" and the Sixth and Second Doctors in "The Two Doctors". In the former it's suggested that the reason the Doctor seemingly can't stand himself is that he's actually more like his past / future selves than each self would care to admit.
 * This is nicely subverted in the short "Time Crash" where the Fifth and Tenth Doctors briefly meet. Five doesn't recognise his future-self at first, and is mostly annoyed that this baffling stranger has broken into his ship and is babbling on about hair and celery. Finally, he works it out, and the two of them share a touching moment. Ten reveals that Five was his favourite Doctor, and he loved being him.
 * However, in "Journey's End", the Tenth Doctor pretty much states that he thinks he's "a better man" than the Ninth, and that his previous incarnation was more violent than him.
 * A strange version in "The Almost People". The Doctor has  It doesn't necessarily mean that Eleven hates Ten, but considering the low-point of the regeneration, there might be some hard feelings.
 * In The Twin Dilemma, Six states that he didn't like being Five. However, he was suffering from moodswings at the time, so it's unknown whether or not this statement should be taken seriously.
 * Given what Eleven has said about himself in general, not any one specific version, it may be the fact that every other Doctor's face is the face of actions the Doctor detested having had to take.
 * In an episode of Charmed, Paige goes back in time to when she was seventeen and is horrified to realise what a brat she was at that age.
 * Samantha Who was about a woman with amnesia and as she puts her life back together is appalled to discover what an awful person she had been.
 * In the American version of Life On Mars, Sam is afraid of talking to himself as a child.
 * Mystery Science Theater 3000: in their episode about Time Chasers Crow is immediately hostile to the Crow of 30 minutes ago because he has to explain to Crow the unforeseen consequences of their time travel.

"Past You: I just want you to know that if we get through this alive, I'm making sure we turn out better than you. No offense."
 * Though, to be fair, when you do the sequel quest "Mystery of the Infinite, Redeux", you're mocked just as much by Past You:

 * Karkat of Homestuck gets into arguments with his past selves so often that it's practically become a Running Gag. And his future selves hate him just as much. He provides the page quote. It should probably be noted that the troll reproductive cycle has two reproductive relationships: one analogous to human romance (flushed, obviously represented by a heart) and one based entirely on mutual hatred (caliginous, represented by a spade). Karkat <3< Karkat is all but confirmed by canon.

 * In an episode of Justice League Unlimited, old Bruce Wayne meets his past self and, during a suspect's interrogation, comments that "I can't believe I used to be so green." Afterwards, Old Bruce teaches his past self how to properly interrogate a criminal, foregoing the traditional method of terrifying the Mook and instead simply beating information out of him.
