I can't say I haven't had the thought, especially regarding my dad, but anytime I go down that road it always comes back to bite me in the #$$. Honestly, if I want to indulge a revenge fantasy, I'd rather these people experience sad, poetic justice. My dad has spent his life insulting, demeaning and abusing the people around him, but is terrified of being alone. The only people left in his life are my mother and myself and my mother is dying. When she passes, I'm not sticking around. I mean, he pushed everyone away. He can stew in indignation and anger at the injustice of it all. Of being alone. Unremarked. Forgotten. It's quite sad, but it's the bed he's made for himself.
