You hope for reconciliation but I don't think it makes him a bad guy if it doesn't happen.
As for the "cheating", I'd guess I'd like to know the circumstances. I personally have been in situations where I actually hit the wrong ball (and was penalized for it). It's a mistake that can be made. It's pretty clear that his personality clashed with his teammates. I would not be surprised at all if that personality clash might have colored the way his teammates looked at the "wrong ball" incident. Pretty easy to accuse someone of cheating, as opposed to a simple mistake, if you have an intense dislike for that person.
