That I actually do have a bad temper and do get angry very easily, that my anger does not justify my verbal/physical reactions (nor was I 'right' just because I was angry) and that these reactions will hurt those I care about/those I don't care about but still didn't deserve my violence, which is a surefire way to end up in jail (perhaps) and in Hell (more likely).

For everyone who has similar issues, try to remember two things:

1. Ambiguous behaviour does not mean aggressive behaviour.
2. The flesh is weak. If you, in your anger, start a fight and perhaps just push someone and they crack their head and die/lose function, you'll never live it down, you will always be the guy who killed someone in anger (and not even righteous anger, you're just temperamental). And it can happen very quickly too! A good man cannot live with that, only a hell-bound one can, so either you'll be oppressed by your guilt or you'll realize you've lost your humanity and you're a full on psycho.
