My [29M] cousin [29M] is like a brother to me and is the godfather to my sons, but he is divorcing his wife for not getting a scar removed and this is ruining our relationship

My [29M] cousin [29M] is like a brother to me. We have the same birthday and we lived next door to each other as kids and went to the same school. We were the best man at each other’s weddings and he is the godfather to my sons [4M] [3M] [2M]. He’s doing something now that’s affecting his relationship with our whole family and making me lose so much respect for him.

In December of 2014 his wife [29F] had a mole that turned out to be skin cancer. She was lucky and it got caught early before it spread anywhere beyond her skin. To be safe they removed the skin around the mole and not just the mole itself. She needed stitches but the surgery was the only thing the doctors did for treatment. The mole was on her stomach and she ended up with a scar from the surgery. I know it’s against the rule to post a picture here but if you put your thumb on your navel and your index finger on your hip bone the scar would be in the exact center. It’s about 2 inches long (the length of the short side of a credit card or driver’s license)

My cousin filed for divorce a year after her surgery because she refused to get the scar removed with laser treatment. He said it was ugly and he hated it. He filed in December of 2015 on their seventh wedding anniversary. He keeps saying it’s not just about the scar but the fact that she doesn’t respect him enough to stay attractive for him, whatever that means. He also says if she had a big accident or was disfigured or something he wouldn’t automatically leave her because those injuries could be serious but the scar she has now would be so easy to have removed. I have lost a lot of respect for him since he did this. He said he didn’t cheat or use this as an excuse for something else because I sure thought that was what he was doing. His wife told my wife [25F] that she had no reason to think he cheated and his phone records and online activity provided as part of the divorce proceedings don’t show that. He is living alone and isn’t seeing anyone and he says there wasn’t another woman or anything else. I don’t know why he would file over such a stupid reason and I am upset that he’s being so moronic and throwing away a good marriage over a scar. Our other relatives feel the same way and no one wants to be around him because he insists that he is right and that the scar was ugly. It’s really driven a wedge in my relationship with him and we don’t even spend time together like we used to. The divorce will be final in a few months. He insists I would do the same thing in his shoes but I would not. My wife has been pregnant three times and I didn’t leave her when her body changed (all aside that I love my wife as a person and not just for her body). I don’t know what to do now or if our relationship can be repaired. What should I do to try and fix things between us?

tl;dr: My cousin, like a brother to me and the godfather to my sons, is divorcing his wife because of a 2 inch scar on her stomach from skin cancer surgery that she won’t get removed with laser treatment. He insists he is right and that I would do the same thing (I wouldn’t) and it’s driving a wedge in our relationship and I’m not sure how to fix things.
