How did he treat Nathan according to you? as for Rachel, I think you're confusing him with Jean, he's always treated her well. As for his friends, they were all fake friends, all of them, his only true friends are the Champions and they seemed to like him just fine, Storm treating him horribly for years speaks badly about her, the fact that he still respected her even when she was talking about how much she wanted him dead all the time says a lot about Scott's good nature, not so much about Storm and the rest of "friends" who were quite ungrateful and unpleasant.
