Ember,
I don't know about a mentor, or hero-worshipping, but my take on it is that during the crisis their outlook changes, and they now view things differently, or find things that support their new world view.
My H, for instance, always thought that certain specific people were nuts, selfish, not honorable, and so on. Now in the crisis one he now praises one of them, and when he was told that he was just like one of the others he said no, he didn't see himself like that, because he continued to provide financial support. Previously he had railed against that person's overall behaviour, now he's found just the one thing to denigrate.
So that's on par with your H saying that he's not acting like your uncle did -- he's finding things to differentiate himself, because he KNOWS that what your uncle did wasn't right. By finding something different, or saying that the other person was inherently bad and since he isn't, it isn't the same, he justifies it all in his mind.
That person's son also wants very little to do with him; a couple of years ago my H was trying to tell that boy that he needs to forgive his father (it was never something that bothered the boy....); clearly worried that he himself wouldn't be forgiven.
It's a mess, to tell you the truth.
