Not to spoil it for anyone but the worst part of the prequels is in episode III when after Anikin kills Mace Wendu in fair combat he is all upset and asks 'what have I done' the next logical step after that moral crisis of killing a trained Jedi? Go to the jedi daycare and kill 50+ kids under 12. Makes no sense at all.
I wouldn't exactly call blind siding someone that thinks you're a trusted ally with a saber chop to the wrist, thus allowing them to become defenseless, blasted by dark force energy and flung out a window to their death as particularly fair.
