Is AUTHOR wrong in the post ? POST : This is stupidly long, sorry.

TL;DR: My brother has anger management issues around losing. This makes me not want to play Mario Kart with him because when he gets angry it stresses me out. However, he really wants to play Mario Kart with me and I'm conflicted on whether me saying no makes me a jerk or not. 

My brother and I have a really good relationship, we're essentially best friends.

I love playing video games with him, and I enjoy watching him play single player games.

We've played a lot of Mario Kart in the past, and the problem is that he tends to be a sore loser. He gets very angry, tends to shout, cry, and sometimes acts violent (slams fists down onto the floor, etc. he's never hit me or anything).

We can't play monopoly anymore because of this kind of attitude towards losing, he takes games very seriously and it sucks the fun out for me and makes me very stressed and anxious.

it's really hard for my to understand how upset he gets over losing a game and I'm worried I'm gonna say the wrong thing and he'll get even angrier, which is another reason I'm reluctant to play with him. 

He keeps saying that he'll change so that I play Mario Kart with him but he never does, and I've brought it up with him several times to explain why I don't feel comfortable playing Mario Kart. I offer alternatives, usually cooperative games where no one can really lose because you're on the same team.

I understand that you can play a team mode on Mario Kart but the issue is even if we're on the same team if I get in first place he throws a fit.

He's not happy with my reluctance to play Mario Kart with him and I feel bad because I enjoy spending time with him but I *really* hate playing Mario Kart with him because there's zero enjoyment in it.

I realize I could purposely do bad so that he'd win, and I guess I'm a stubborn jerk for admiring this, but I don't like purposely losing. It feels unfair to the other person.

Apologies for how long this is, it's just been eating at me because I feel really conflicted. He *really* wants to play Mario Kart with me, and I feel terrible turning him down.

I want him to be happy but I also want to be happy. Am I the asshole?
