Don't be cruel, Nightmare...sure, he was a jackass. Sure, he was crude and rude, but no one deserves to die, and certainly not for something like this. In the end it's not but an inconvenience and a loss of friendship...certainly nothing to stay angry about for weeks on end.
So, Herograw, what I hope is not that you die in a car crash, or for you to "enjoy your AIDS" or whatever...what I hope is that you honestly and deeply think about what you have done, understand why it was wrong and come to grips with what caused you to do it. Learn from the experience and become a better person.
