We doesnt know much about Dookus turn. Not how long it tok or any details about how he choosed the dark side. Thats why it seems more believable when Dooko did it... I am willing to accept how he did it because its more mystical. As for Ani believing in dictatorship or not believing in Jedi order is not true (where did that come from?). He always believed in Jedi in theory and doing good and serve others. Yes, I doesnt always agree with the Jedi order, but who doesnt..!!! "To save Padme" and "Fear of losing Padme" are actually the same thing in this case.
