The finished product in ROTS, is that the Jedi did not trust him throughout the beginning of the movie, and in fact they were conspiring against him, Obi Wan tries weakly to back him but ultimately falls back into his place rather than risk losing is standing with Yoda and Windu & his place on the council. Yoda and Windu were not good masters or friends to say the least, they pretty much prejudged him, found him guilty upon suspicion and already forsaken him along with abandoned the whole prophecy" thing , they pretty much feared him and had no use for him. Obi-Wan himself was neither here nor there as a friend or master, he appears jealous of Skywalker and there was always some tension due to Padme and Skywalker and Kenobi were both egotistical and headstrong. All the while in AOTC it was Obi Wan that had questionable objections to Anakin and not Yoda or Windu and they were backing him. Not trusting him and alienating Anakin was the catalyst which finally drove Anakin away from the order, they were also setting him up by asking him to spy on the Chancellor, had they trusted him they wouldve made him a Master, this was an insult to him, they were taking out their anger on Anakin rather than challenging Palpatine directly. They do things Jedi should not do and against their own code, so they come off as hypocrites and passive aggressives . Anakin if you pay attention did not turn from from Sidious' temptation of abandoning Obi Wan onboard Grievous' ship, he said his fate with theirs to Palpatine's surprise and that was shortly after he attempted to gas up Anakin's head by justifying Anakin's doubt and remorse over killing Dooku. During the opera, Anakin rebutted Palpatine temptations and during the chamber meeting again refused his temptation. Windu refused Anakin the honor of aiding in the arrest of Palpatine which was a smack in his face and blatantly said he did not trust him flat out. Anakin was refusing to aid Palpatine during his fall at the hands of Windu, only when Windu again refused to honor the Jedi code by taking him prisoner and disregarding Anakin's plea as their was still information or value in keeping him alive did Anakin finally act by wounding Windu. He did not realize Palpatine was lying about being near death, by that time Anakin questions and shows remorse and a sense of loss as he was betrayed by Palpatine and Jedi. Probably no surprise Anakin by Mustafar wanted to get rid of Palpatine very soon and he was just mopping up all enemies of both the Sith and Jedi, he appears to see himself for himself by Mustafar. Obi showing with Padme ignated his hatred for the Jedi and felt padme brought him along to assassinate him and well Anakin already had murdered or killed many Jedi and youglings and there was a sense of self guilt, fear and point of no return. With Lucas' storytelling and finished PT movies, the council and Jedi were of dubious sanity, ethics and morality themselves I really cant blame Dooku or Anakin for turning out the way they did.
