I never met this char and I don't really play much anymore (mostly just troll the forums), but this, in my opinion, can all be drawn back to Karithia. A lot of people back around that time didn't think that sort of "back handed good" should be rewarded, and its led to a string of irritating and abrasive characters that, while possibly RP'd "ok", are incredibly frustrating to deal with when you're good aligned and have no means of retaliating against the string of insults.

Now, I'm not trying to drudge up the past but I think the take away lesson for me is that we should strongly discourage this type of "roleplaying" where in its basically just players abusing the fact that other good aligned people cannot retaliate against your rudeness.

I don't like characters rolled specifically to grief their allies.
