Cornered Rattlesnake

""That is exactly what the harboring of hate and resentment against others is - a biting of oneself. We think we are harming others in holding these spites and hates, but the deeper harm is to ourselves.”"

- E. Stanley Jones

""Put the army in the face of death where there is no escape and they will not flee or be afraid - there is nothing they cannot achieve""

- Sun Tzu adressing this trope

The "Cornered Rattlesnake" is when a character or a faction is pressured to the breaking point. Another group or the 'big bad' will bully or threaten the weaker 'rattlesnake' until the weaker person fights back. Sometimes the 'weaker' group is actually surprisingly powerful, but the bully underestimated their abillities. Having the rattlesnake 'bite back' is something the big bad normally didn't intend or anticipate, and so he will face the consequences.

Sometimes a Cornered Rattlesnake will be given assistance from the enemies of the 'big bad bullies', and so will begin to be able to defend itself. The 'big bad's' cruel actions could actually make their allies turn towards the 'rattlesnake's' side.

The phrase refers to the real life scenario of if a person were to corner a rattlesnake. The human can easily choose to retreat, but instead tries to kill the rattlesnake. Cornered, the rattlesnake would defend itself. This trope doesn't require the rattlesnake to win, as it is possible to kill the snake, but being bitten is highly likely.

Sometimes this is a response to a No-Holds-Barred Beatdown, Hopeless Boss Fight or Curb Stomp Battle.

This isn't Bullying a Dragon, as the cornered rattlesnake appears, at first, to be physically weaker or a huge coward and only reacts in self defense.
