The Clown Prince of Crime
Super Freak
Hell, if Yoda was so damn smart he should have trained Luke about Sith lightning. Luke could then just zap Vader easily besting him. And teach him the block/absorb to beat the dude that kicked his ass
.
No need to teach Luke ****. As the last remaining trained Jedi, he sends Luke alone to face off against Darth Vader: who he knows to be stronger than his son? What? While training Luke, he is revealed to still be very powerful (lifting the entire Fighter with no effort). So it makes no sense that he wouldn't join the Rebellion cause, if only to provide strategic input or being carried in a back-pack to assist Luke in his fights. Instead, his wise decision is to leave Luke on his suicide mission and thinks no further of it....because he had to make a soup, apparently. Soup is more important than the fate of the galaxy.
