Yea I know, I'm a total scum bag.
Instead of calling yourself names, in a rather amusing tone, you should be feeling remorse, or guilt for your uncalled for actions. Sure, apologizing probably isn't an option, but thinking about it as a laughing matter shouldn't be an option.
I am not trying to make you feel bad, or am picking on you. I am just trying to make you realize that your actions, no matter how you think they don't, do sometimes have consequences. What if that guy became a bully because of your beating him up, and a result, caused another innocent person to feel pain, and anguish? What if that person decided to kill themselves because of that?
Okay, I might be over exaggerating here, but think I do make a point. Beating up people for no apparent reason is not acceptable, ever. In fact, beating up a person at all isn't acceptable. There are more mature and constructive methods and actions you can take. Believe me, I, of all people, know what its like to experience periods of extreme and unbridled rage. Its all a part of my particular manifestation of Bi-Polar disorder. I used to take my rage out on people, once even stabbing a fellow classmate on the back of the hand with a very sharp pencil in elementary school. Not my best moment.
That was long before I was diagnosed, and before I took the proper medication to manage it. Back then I didn't know it was not okay, but now I know that it wasn't. Its never okay to inflict pain on another person, no matter how much you feel they deserve it, or how much you think they can handle it.
