It's too bad that Episode 7 totally ruined Luke Skywalker's character for me. Luke, the character who would literally drop everything and go to any end, even to the point of short-sightedness, to help his friends and save his family. We're supposed to believe that he simply disappeared for decades because his Jedi Academy failed. The character who was the embodiment of heroic sacrifice and loyalty, is perfectly content to sit back and let his creation wreak havoc across the galaxy and abandon his friends and family because sadface feels.
"He just... walked away from everything."
Watch as the character of Luke Skywalker is completely destroyed by one line of dialogue.
