Leaving Vader alive results in Palpatine’s defeat and the fall of the Empire (at least until Palapatine returned “somehow” lol).
“Many that live deserve death. And some that die deserve life. Can you give it to them? Then do not be too eager to deal out death in judgement. For even the very wise cannot see all ends.” to bring a bit of Tolkien into the Star Wars chat!
Anyway, I stand by my point that a Jedi executing a fallen foe would be completely out of character with the compassion and chivalry that is their code.
But Ben smelling piss (to the point a jawa can hardly stand next to him) and not helping a fellow Jedi are “in character” ? Something people just reinvent anything to shoehorn inconsistent stuff.
Something it’s easier to say “yep true it’s not great and not very consistent, but I like it nonetheless”. I like ROTS, I still find it’s failling in many places, I won’t just make out of the blue assumptions to defend any single stuff about it especially shitty stuff.
