Why do people place all the blame on incels?

You can say it's their personality, they hate women, etc, until you're blue in the face. But that never stopped really good looking guys or women from getting laid. Also let's be honest, you'd be super frustrated and it'd effect your mental health too if you weren't getting sex and kept getting rejected. It just seems fucked up to bully and push these people. Many end up shooting up schools or committing suicide. But it's somehow justified to attack them and have them end themselves because they're frustrated that they can't get laid?
