Oh I get what you mean with those characters. I'm okay with those, especially if it costs them something, like a memory or a lost power. That's the thing I've always hated with Wolverine (and by extension, Superman). We almost always know that they're going to survive the fight intact. There are no stakes. If anything, only collateral damage. When they die, other characters should just expect them to come back. Other than that, their grief wouldn't come across as believable. Dead should be dead, and they should have another character take up their legacy instead.

I had a burrito at the time, but I had a kebab the other night so win-win! And it was all before I read your reply haha! Thanks for stopping by, mateychops!
