Mom looks like an enabler and probably wasn't very involved with the kid early on, hence why she is willing to take his crap now. Oh yea, where is dad? Unless there is something inheritenly wrong with the son's psychi that drove him to this, not having a male role model and a mother who doesn't look like she gave a crap could easily end up this way. Just a quasi-educated guess from the present story.
