I can somewhat see Anakin seeing Mace Windu as a traitor, and that's even pushing it. Anakin almost Killed Palpatine when he found out about his true nature. He killed Dooku as well because he was a Sith Lord. Anakin killed 5 year olds, he killed the very people that took it from a slave on tatooine, and turned him into a jedo hero that was known all over the galaxy. There is a reason the Jedi masters didn't want him to be trained, and they where proved right.. The galaxy would have been better off had Anakin stayed as slave and died as one.
