I must have killed millions of virtual people by now...perhaps into the billions if you include populations of cities that I've nuked in things like Civilization, DEFCON and the like.
I don't think I've raised my fist in anger in reality for about eighteen years, and I try very hard not to even hold grudges.
Of course, it all depends on the situation, I'd like to think I could give a good account of myself if the moment demanded it, but generally speaking I'm pretty pacifist. I usually talk myself out of any problems I get in.
EDIT: Oh noes! It's Torplexed
(he should really have a goatee...)
