Even your neutral character will probably slaughter a gazillion innocent mobs to get their armor, or just to see what happens. ICly there's supposedly no difference between players and mobs (but that standard kinda fluctuates depending on the situation).

Anyway, you'll probably be killed by someone for a reason unknown to you. Just avoid assuming that it means they aren't roleplaying. The question "why did you kill me?" is usually bad enough (most roles indicate badassedness), but throwing a hissy fit and going OOC because you don't get an answer or because you're not satisfied with the answer is sillytarded. It used to make me multikill people, but I've since matured.

Read up on 'duo dimension' and go make that two-dimensional killer
