Yes, because it’s society you’re mad at, not yourself, and everybody is mocking you by having it better than you.
It’s also in part why young white males tend to be the predominant perpetrators of this kind of thing. They’ve been told all their lives that as white men, they are basically in charge because they are the highest up in the pecking order, and when they find out it’s not actually true, when they see that the rest of society is working against that idea, they are sorely disappointed, because no one told them there were limits. They were lied to, it’s just not right, and now someone has to die, goddammit.
