I'm going to get my co worker fired
Is there a point behind trying to get him fired?
I just want to be a jerk to him.
Your mission is to make someone very frustrated, that is quite clear to see. Put yourself in their place, and ask yourself would you want this to happen to you. Being fired could mean he becomes homeless, and then lose all of his friends.
It's not like him getting fired will make him lose any friends, he already had none to begin with.
I think that you should not do that. I think that it will look bad on you if you make your coworker lose his job.
