Me: What’s wrong with being happy when your team wins and mad when they lose? You: Nothing

I must apologize.

I re-read your post with the "Me" statement above. I thought the "your" meant the fans, not the players, that's why I sad "nothing".
I meant for the fans it's OK be happy when they win and, I'll use the term "unhappy" instead of "mad", if you will allow me, when they lose.
It's also OK for the players to feel that way, too, but not take it out on the opposing team's players!

But Malkin doesn’t take it out on opposing players. Again, that would show up in the stats as penalty minute and suspensions, he gets very few of the former and none of the later.
