If Darth Vader hadn’t killed all the Jedi, there’s NO WAY Luke would have become a Jedi Master. Not for lack of talent, and definitely not because of the Dark Side, but dude, Luke Skywalker trying to comply with the “no emotional connections” policy?
The Council would be like “Luke, stop making friends, it is the Path to Corruption”
and Luke would be like “What? It’s only Han”
“What about these other 356,739,000 people you made friends with?”
“They’re really nice! If you got to know them-”
“And you and your sister need to stop saving each other. Only we can authorize rescues. Connection Is Bad.”
and so Luke Skywalker fled the Order in the dead of night, never to be seen again, except by his 356,739,000 friends, many of whom are in the Jedi Order anyway
