I used to live near Rittenhouse's town, and you might think it's full of irredeemable reactionaries and neo-nazis, and maybe it is. I haven't been there in a very long time. However, back in the day, with people from around there that are old enough to be his dad, I organized a union. So, what I'm getting at is that Kyle probably has no excuse. There was almost certainly visible alternatives to the barbarism route that he chose. I've got to imagine his parents are real pieces of work though.
