Im sick of this cat

Hes not even a year old but im going to have to return him to the shelter. He doesnt get along with my other cat, he's aggresive and frankly a dick who ruined my whole apartment, couldnt get my deposit back. Never had an issue with the other kitten. I feel like a dick but i cannot live with him anymore and i dont want to throw him onto the street :/ if it wasnt for covid or his behavioral problems i probably would have been okay with him but now hes become such a burden i cant take it anymore
