For those of you who are questioning Luke’s actions- he’s suffering from severe depression. Depression can really fuck with you and speaking from experience you do stuff that’s not normal for you.
Yes, but the question is down to whether Luke Skywalker being depression-prone is tonally consistent with his character as established by the OT. Obviously anyone, even Luke, could succumb to depression, but that’s like saying Superman could feasibly get fat and bald. It’s possible, but does it feel right? Luke’s entire victory/arc in the OT was about his mastery of his emotions, his darker impulses. One could reasonably assume that such a person wouldn’t succumb to depression very easily. For a lot of fans, the leap from ‘eternal optimist and Jedi Knight’ to ‘defeated hobo’ is too jarring - not so much because of fan conservatism but because it doesn’t feel realistic in the context of what has gone before.
I’m not sure how I feel about it myself, but I do get why there’s a controversy here. (And by the way this post is in no way intended to trivialise yours or anyone’s experiences with these things.)
