Why did the guy in Canada Behead that guy on the Greyhound bus and eat him?

Question

What set him off, why did he chose that guy, where they arguing or what?

Answer 1

Li, the attacker, is the only one who can answer that and he isn't talking at all.  Not even in court.

Answer 2

Because he was INSANE IN THE MEMBRANE, INSANE IN THE BRAIN!!!!

Answer 3

No, there was no argument or talk at all.  The victim was just sleeping with headphones on, as most people do on a Greyhound ride.  My theory is that because this killer just lost his job at Walmart, he wanted free room and board for life in a country that doesn't believe in the death penalty. No work. Just narcissm.  He'll probably get a website with thousands of fans. To say "what set him off " or why did he choose that guy suggests that the victim was at fault and "asking for it" by wearing a mini-skirt (whoops, rape victims to blame for being raped).  Whelp, just seems the guy preferred being famous for gruesomeness and spending life with room and board than working at Walmart.
