The excuses for it are irrelevant, since he'll make them up if he needs one. The underlying problem is: he feels so powerless in his real life, with the loss of his child custody being the last straw; that the only place he could find any sort of control or power was by being a verbal bully on the CSB.
He became a troll because it was the biggest form of attention he could get; negative attention.
Unfortunately, someone took advantage that and pointed him towards targets, then patted him on the head for being 'strong', so far sadly, he doesn't realize he's being used.
I saw that manipulative side of Gwen from all the 'thanking' she required. So like my mom; it isn't really your gratitude she wants but your indebtedness; your dependence on her. ~Steve has swallowed that hook, line and sinker. What guy wouldn't want that- power and a pretty girl who thinks he's a big, strong man?

Tell him that though, and you just feed the troll. What he really needs is too get away from his keyboard, get outta that kitchen and go out in the world. Maybe find a real girlfriend and get laid!
