I want to kick my roommate
Why do you want to do that?
It's just that I have never got along with him since the first time I saw him.
It may sound like it would be cathartic to kick your roommate, but physical violence is never the answer to interpersonal problems.  This is harmful, and potentially dangerous behavior, and your roommate would have the right to report you to the authorities if you assaulted him.
I'm strong and I'm going to kick his ass like a badass. It will feel so good to take out all my anger on him.
You may very well be strong enough to do so and get away with it.  What I'm trying to tell you, however, is that there will almost undoubtedly be legal repercussions for what you do, and they could be quite serious!
