Luke, I disfigured your father
Obi-Wan, you judgmental piece of garbage! Calling your former Padawan “twisted and evil” and “more machine now than man” is all your fault. It was Obi-Wan who chopped of Anakin’s legs and most of his left arm. Obi-Wan left Anakin to fall slowly into the lava. This “Jedi Master” left Anakin to fall slowly into a pit of lava.
And because of all of these things, Anakin had to get fitted for multiple prosthetics, a new voice box, and all kinds of machine-like components. If Darth Vader is more machine than man, it’s because of you! Now you’re turning Luke against the very man you disfigured. You manipulative old fool!
