LOL! I responded to a guy complaining that Thor changed, pointing out that Thor explained to Loki himself why change is good.
AND HE BLOCKED ME! Some people can't handle the truth 😛
I'm sorry, but Thor himself addressed this in Ragnarok. After Thor's hammer broke, he changed as a person. He grew. He tells his brother just as much.
He was then traumatized by the Infinity War. That sort of experience changes a man.
