Don't want to be remembered as a jerk and have your death celebrated? Don't be a jerk.
His death doesn't absolve him of the despicable things he did while he was alive. It just means he can't continue doing despicable things. Which is a good thing.
Your behavior is that of a jerk. Do you want to be remembered as a jerk?
Don't really care, to be honest. I won't be there. Nor do I care about my funeral, where (or if) I'm buried, or any thing else post-death.
But please tell me how my behavior is that of a jerk. I'm of the opinion that someone's reputation should be based on what they did while they are alive. How does the act of dying change or otherwise mitigate a dead person's despicable actions?
And how does pointing that out make me a jerk?
Celebrating the death of a person is generally a jerk move. No, he wasn't Hitler.
