RE: Why doesn’t Ben kill a defeated Vader?
Jedi Knights are honourable and chivalrous. Killing an opponent in a duel is one thing, but killing a vanquished fallen opponent is something entirely different. That is an execution.
We already see that when Anakin ‘executes’ a defeated Count Dooku. It is a wholly evil thing, and not the Jedi way.
Really? Well i would have a word with Mace Windu then. he was quite happy to Kill Palpatine to “end the Sith”. And what about Kenobi and Yoda? They wanted Luke to kill Vader. They didn’t say “you can only kill him in a fair duel”. Obi-Wan just said that if Luke couldn’t kill Vader, then the Emperor had already won.
