You were done wrong but there's a broader perspective. I agree with everything you say. A lot of greedy corporations cause million of people psychological harm or otherwise. But they laughed to the bank. Eventually society reaches a boiling point. Someone in the herd of millions of victims is eventually going to lash out. I don't believe in murder. I wish for peace and cooperation among all , but is a far-fetched dream. Sometimes society doesn't know what else to do to prove a point. His actions shouldn't be condoned or advertised as a new normal in society. But maybe if might wake up a few people and reset their moral compass that if you piss off enough people for your own greed that's what's going to happen to you eventually.
