How is this behavior of me in principle, is he himself guilty?

He always rages on youtube and twitch

I write in chat, how bad he is, I'm glad if the opponent scores a goal. And then he throws his controller against the wall

now he always says I owe him 60 euro? If he does not have his aggression under control?

You owe him nothing, at least no money

But maybe you could help him instead of annoying him

Nice week
