I don’t think so, and I’m a theology professor, but granted, I don’t teach moral theology unless I’m subbing for a vacationing teacher. I have taken lower and upper level courses in moral theology, though.
I’m not sure if you want to be an actual wrestler, like in the Olympics, or a one like in the WWE.
I don’t see anything morally wrong with either. If you are a “real” wrestler, you are participating in a sport.
If your goal is to be part of the WWE, then you know it’s scripted; the supposed violence is just that - supposed. No wrestler in the WWE intentionally hurts another wrestler. Dolph Ziggler and the Miz are best friends.
I admit to watching WWE wrestling. I have a third degree black belt in taekwondo, and I also watch MMA as well.
Good luck!

and when the McMahons start promoting you as much as Roman Reigns, who I like, be sure to give some of that money to worthy charities!
I see nothing wrong with it.
