"If a guy brings me his code, and it has mistakes, it brings insane pleasure from how smart I feel ... And if you tell me that you haven’t had this feeling ever, then you’re lying." Wrong on so many levels. Taking pleasure from someone else's mistakes is a sign that something is wrong with you. That is all. The only thing that is exceptional is that this industry has a high tolerance for this behaviour. It also sounds like this guy is destroying value. If you are such a poor manager that you try to get rid of someone rather than bringing them up then you are a net negative. Again, I have come across this in other industries: the manager will go before the junior. No question. Writing bad code is nothing compared to the impact on culture of one bad apple.
