Who is right in the dispute?

Me and a friend always play Minecraft together. He lives one city away but we know each other personally. I killed him while he was afk because he was standing in the way and I apologized later. Then he killed me, which I found a little unnecessary. Then he killed me 5-6 times and annoyed me.

In any case, it's not about the game but about making it real. He always has to have "revenge" for what doesn't suit him. So "if you do, I'll do it back". He says it's fair and I say it's childish (you could just leave it at that). How do you see it?

Those who seek revenge are never in the right if it is only about revenge as an end in itself.
