It's obvious that most of the Rebels die anyway. They don't appear in the original trilogy, because they are dead, and Darth Vader needs some Rebel scum to kill to cement his portrayal as a cruel, menacing Sith Lord. Tbh he was pretty tame in the original trilogy.
Although I agree with you. Just how lonely and isolated are some of the teenagers on here that being a jerk is the only way to recieve attention.
