I disagree. For one a person who experiences trauma is never the same after such an external “disturbance”. This is the very nature of trauma, and Luke experienced trauma in more ways than just physical injury. He went to Cloud City, believing he might be able to save his friends from the clutches of the man who murdered his father, only to come up one hand short, and discovering that his noble hero father is the ultimate bad guy. A man is, what he believes in, and everything Luke believed, has turned out to be a lie. I would call that a life changing event. The Luke at the end of TESB definitely is no longer the naive young rebel he was at the start of the film. He is now a Jedi in training, who’s life has been turned upside down. The idea that he would just get a new hand, and go on as if nothing has happened (which is what you seem to suggest) is ludricous to me.
Imperialscum, you are going to have a hard time winning your debates when you keep running into solid posts like these.
