I mean he's a 19 years old teenager filled with hormones and rage. I always wondered what the Jedis expected in the first place when it was so very clear from the start Anakin wasn't sublime above such feelings like a "usual" Jedi student? Also Yoda said from the very beginning he was already too old when Qui-Gon discovered him. Obi Wan whatever more felt responsible for Anakin because of his masters sudden dead and his loyalty to him. So many things went wrong from the very beginning for Anakin. But yeah his arrogance and superior behaviour was a huge character weakness no one could handle. Not Obi Wan, not Padme, not Yoda not anyone. So he was a pretty easy target for Palpatine and his false promises and manipulation especially when he had such thoughts in his head pretty early (after his mothers dead). He's guided by his emotions and never by his head what makes him pretty much everything but not so much a Jedi. I mean in the end he kinda was "the chosen one" to destroy everything lol
One of the things we find in ‘Revenge of the Sith’ is that the dark side is not tempting Anakin to anything... that Anakin is looking at the dark side and saying, ‘That’s what I want.’
