Nope, never started a fight, as in swung the first punch. Now, instigated, on the other hand... heh.
But seriously. I'm afraid of pain. It's that simple. I've been in a couple fights, but I never started any of them. I've been bawling my eyes out and still swinging--kinda Cool Hand Luke style--and they walked away as having won, which they did. But I've not been in a fight since Primary School.
Like I said, I don't abhor violence. I love seeing the Bad Guy get thrashed as much as the next person. But, the Good Guy doesn't swing the first punch (extraneous circumstances notwithstanding). And unless it's life or death, the Good Guy doesn't beat the Bad Guy to a pulp, unless the Bad Guy just won't quit.
Which is why my last Chronicle, with my character killing the slimeball, is such a huge fall from grace for him.
