...I don't really know all the details, but...
Keisuke had been...bullied, in high school, apparently. He was turned on by the people he wanted to protect from bullying. When he read the LaPlace mail that said you were going to be lynched, I guess he...couldn't take it anymore.
He was so angry...it didn't help that the police were starting to abuse their power, that they were killing people with their demons...Keisuke was so angry, he...managed to contract Yama, the Judge, without a COMP.
[It's difficult, to remember so many different things.]
