_Sublime_Skywalker_ posted:Luke knew because he felt some of the hope in Vader. Also, Anakin's always been a sucker for attatchment, and whether he knows Luke well or not, he's still his son. So therefore, when Darth Vader didn't kill Luke on Bespin, and kept procrastinating to finish him on the DSII when he refused to fight. That was a sign that maybe Darth Vader wasn't 100% evil.
