Logan/Wolverine has been around for a long ass time, and by all accounts in just about every conflict since the 1800s(one of my favorite being the Spanish Civil War, on the Anti-Francoist side)….
He’s been in a lot of foxholes/trenches/bunkers, with a lot of scared and lonely people(predominantly men, but some women).
Add that to the fact that he’s super old, and becoming jaded about social mores is a no brainer trope when it comes to immortality…(Dorian Grey, Lestat, Captain Jack Harkness, just right off the top of my head).
