I’d personally at least try to remove at least ‘all the’, so that it’s just ‘I… am… Jedi’
I agree with you, it also hearkens back to Luke’s “I’m a Jedi, like my father before me.”
Yes! “I am a Jedi” it’s much better, it also implies that just by being a Jedi you have help from the others, because they are together in the Force, making clear the difference to the selfish Sith.
