... he described the traumas that shaped him: His biological father was never part of his life... producing a feeling of “abandonment shame”; his grandmother once scalded him with hot water, ... leaving a scar on his back... he was bullied in high school.

Bitter over the end of a long relationship, estranged from his children ... He wrote angrily about the breakup of his relationship with Taub and accused her of destroying his relationship with his children.... the chaos in the household shortly before they broke up had taken him to the brink of suicide.

Crazy conspiracy theory, but hear me out.... maybe he was damaged by the lack of a father and being abused as a child, and then traumatized and driven into insanity by divorce and alienation from his children.

Nah, too crazy, it must have been Gamergate... and all that misogyny!
