I agree with those who say that the movies themselves cannot be interpreted to support the claim that the Jedi are evil, unless the interpretation is an implausible stretch. However, I think the extreme position taken against Anakin by some people is an equally unsupported stretch of what we see in the movies. By the time he says the line about Jedi being evil, he is lost, but he is a fallen hero, not a villain from the beginning, and his actions remain basically good up until the middle of ROTS, with two glaring exceptions (Dooku's murder and the Tusken slaughter), both of which Anakin recognizes as grave mistakes, demonstrating his continued capacity to recognize right from wrong. Anakin's love of Padme and his desire to protect her are not evil or greedy, but noble and heroic. The way he handles those feelings is wrong, and thus ultimately turns out very badly, but the feelings are not wrong. Compassion and attachment may be different things in a well reasoned ethical framework, but in human feelings (even Jedi feelings) the line between compassion and attachment is blurry and not all feelings of attachment are wrong. Yoda does not say that emotional attachment to a person is greed. He says, "Attachment leads to jealousy," and even jealousy is not greed according to Yoda, but "the shadow of greed." Yoda explains that getting too emotionally attached to people can lead to a character trait that is like greed, admittedly a danger worth trying to avoid, though I don't think the hard line PT Jedi position of training infants and forbidding marriage is the only way to deal with the danger. The twisted, wrong thing about ROTS, the thing that makes the movie compelling, is that Palpatine does not recruit an evil follower. He does not even tap the dormant evil within a good person. Rather, he takes a person with no real greed, in the true sense of that word, and corrupts him anyway by turning the opposite of greed, love, into something perverse for our hero, so that he acts as if he were greedy while trying to be selfless.
