From what’s actually shown in the movies I always assumed Anakin enjoyed being aggressive to win battles. He would have naturally grown impatient with the Jedi teachers and taken the easier path. It’s a far more human response to their doctrine. Instead of all that “I need the secret to preventing death” nonsense. The only part that makes any real sense is his anger against the Tusken Raiders. But it falls down because we don’t ever see how that anger gives him more strength, and there are no repercussions. Where is the fallout or his anger towards Obi-wan and the council for letting this happen, or letting the slave trade continue? What does he learn from the experience, did he enjoy killing or see how rage is a powerful ally? It’s basically forgotten instead of being a genuine part of his character development.
