Which part do you disagree with? Do you think well adjusted people (even within the context of the DCU) do the things costumed individuals do? Hiding out in clubhouses and punching problems are not mature acts imo. Someone with the intelligence of Superman or Batman could do a lot more for humanity with their brains than their fists, but they put their underwear on over their tights and wear capes instead. I love all that stuff but it's also ridiculous. In a story where we're looking at them as though they are real humans, I don't know why they would have nuanced and sophisticated ways of treating their issues. They're doing what they always do, which is repeating the same behavior expecting a different outcome. They are denying that death should play a part in their lives and that they will have to process their grief in a healthy way. They are applying superhero logic to superhero problems.
