Why would he? That's just stupid. You could severly cripple the Empire by killing Vader, and you decide to give up your life?
Anyways, where in the AC does Lucas say Obi-Wan is the strongest good guy?
Also, in the ANH Novel, written by George Lucas, describes them as being equals, and describing Obi-Wan as trying to defeat Vader... So maybe Vader and Sidious are a hell of alot stronger than we thought.
Ok. Lets look at it logically. But before anything, I say Padawan Kenobi would defeat his older self.
And here's why. It's simple.
Darth Maul can defeat Ep1 Ben Kenobi. Plain and simple. Who ever disbelieves that is a scatterbrain.
Darth Maul also singlehandedly killed Obi Wan's master -Jedi Master Qui Gon Jin-
I don't know about you but when a mere (young) Sith apprentice can go toe to toe against a Jedi master and defeat and kill a him fair and square, it has to mean something. Qui Gon was no slouch either. He was might've been considered for a High Counsel position among the greatest Jedi.
Padawan Kenobi defeated Darth Maul. So if Darth Maul would lord over ANH Ben Kenobi yet padawan Kenobi cuts Maul in half, it would make sense that Padawan Kenobi would clearly defeat his older self - ANH Ben Kenobi.
