AITAH For leaving out a friend for his complaining?

FYI post talks mostly about online games. If you aren't familiar maybe don't interact with this post.

For the last few months I've been playing online games with a group of friends and their friends. One person in particular I'll call T.

T, no matter what game we play complains and blames quite often. Especially playing games like Overwatch. Every match whether we win or lose he's complaining.

Every time he dies, it's a random teammates fault, or ours if one of us happens to play support. Every match we lose it's because our randoms are shit, or the enemy is cheating. They never take the blame themselves, and yesterday I finally got angry and yelled at them for getting mad at our support player for not healing. Along the lines of 'Dumbass, they heal by existing next to you!'. I hear a click, not a word from them the rest of session.

Next day we created a discord gc and left him out of it so we could play in peace for a while.

That sounds mean at first. But I did this after being told that my friends have had conversations with him about the complaining yet he continues to do so.

Turns out one of us forgot to appear offline and he joined us, immediately texts one of my friends to ask what's going on. He explained, now T wont talk to us.

AITAH?
