i think he was a loaner and socially awkward his whole life (zero friends) and then finally got attention from a girl. And when that ended he couldn’t handle it and something in his mind snapped, kids flip out all the time at college, they don’t go as extreme as this guy but many kids have break-downs in college. I still remember this one kid that lost it on my dorm floor my freshman year, hearing him scream at his mother over the phone about how his dad was an alien and controlling her and his sister by invisible hooks into their brains was pretty damn chilling.
