2. Putting Anakin Together With Padmé And Then Palpatine
It was clear for all to see that Anakin, even as a small boy, was mentally unstable. Yoda identified him as having these problems from the very beginning So with that emotional groundwork in mind, the worst that the Council could have done was to put him with the woman whom he is still madly in love with... alone and for an extended period of time. That will surely help the whole celibacy thing along nicely. The traumatic events that occurred during his early training with Obi-Wan still plague Anakin, as does his fear of losing his mother. He was not ready for any kind of solo mission by Episode II. While his official mission directive was to protect Padmé; Anakin was too emotionally unstable to cope with the maturity and control needed to restrict his human desires enough to actually protect her. What was wrong with sending Obi-Wan? Padmé has a past with him, and I assume would have trusted him just as much. Then after being corrupted by his personal passion and anger. The council tasks Anakin to "watch Palpatine." This is another awful idea. Again the council doesn't trust Palpatine to begin with, but do they allow him to get extremely close to a potential risk anyway. Mace Windu even spells it out for us; "It's very dangerous, putting them together. I don't think the boy can handle it. I don't trust him." Palpatine uses their time together to mould Anakin into Darth Vader and pave the way for his complete fall to the dark side. Anakin fell to the dark side while trying to save Padmé from death and was guided the whole way by Palpatine. These were both as a result of orders given by Yoda's Jedi Council.
