The Addams Family (1964 TV series)/WMG

The Addamses really did love Debbie.
When Debbie, and asked them whether any of them really loved her, Gomez calls for a show of hands, and all the other family members try to raise their hands. Thirty seconds into Debbie's (unbelievably selfish) Start of Darkness monologue, Grandmama seems totally on her side, and the entire family seems to sympathize with. Debbie had a hint of the family in her, but was just too selfish to see that she'd found a home and family that could love her for what she really was.

The Addams Family are a state of mind! Or a mental disorder.
Literally, the Addams family (Gomez, Morticia, Fester, Granny, Pugsley and Wednesday) are what you become when you visit the Addams house and, instead of running away, start to empathise with them too much. It explains the slightly different versions of the family in the different adaptations. Luckily, along with a propensity towards enjoying torture and violence, you also become imbued with a supernatural toughness and regeneration that will even bring you back from the dead and will somehow 'inherit' (from a family member that never existed till then) a large and spooky manor complete with a bottomless fortune, a huge butler, a friendly severed hand and any number of family members. Of course only one such family exists in any given world, which is why all the different adaptations are all canon.
 * You Kill It, You Bought It. Kill an Addams, and slowly, you become that Addams. That is the true meaning of their family motto.
 * There's also a middle ground. The Addams Family is a state of mind, yes, and once you start to like them, marrying into the family (like Margaret Alford) comes with nigh invulnerability.

In Addams Family Values, Wednesday and Pugsley really did just want to play with the baby.
It's been demonstrated that their definition of "play" involves axes and electric chairs. There's no reason for them to assume that their brother would be any less Nigh Invulnerable than the rest of the family. So, while there may be some legitimate sibling rivalry, the attempted guillotining and repeated drops from high places are just normal Addams playtime.
