It sounds like you've already made up your mind. Maybe you should talk to your manager about why you haven't fired him already. Maybe he has more seniority than you in a way. Also, be honest about the situation. It comes off as partly that you absolutely do not get along with him. But you only mention performance defects. To the degree that it makes it sound like you are looking for more of them to list to distract from your personal disagreement. Either he can be fired, put on another team, you move to another team, or you resign. Need to discuss with your boss.
