So this psycho feels that by killing people associated to wrongs that have been committed in the past to him and in general will actually improve how things are handled?
You know, I'm not a politician or a peacekeeper or anything, but when people are scared, the FIRST THING that happens is a witch hunt. It's not about resolving the problem indefinitely, but about ending the immediate threat. So....idiot goes around shooting people, he's #1 on the list of problems to be solved. He dies or is apprehended, and people are satisfied. Nothing changes.
Hooray for useless morons, I hope he eats a round in the forehead.
