Who is to blame for Anakin's fall
This is a vitally important question. What caused the fall of Anakin Skywalker, an event that has had arguably the largest single set of ramifications in Galactic history?
I firmly believe that there were many factors that led to Anakin's decline into the evil Darth Vader, from Palpatine's machinations to Anakin's own inner darkness. However, it is clear that there is one major individual responsible for the transformation of one of the most powerful Jedi in history into the chief destroyer of the Jedi Order. That individual?
Ki-Adi-Mundi.
This vile individual had the chance to arrest Anakin's decline for two critically important reasons.
Firstly - one of Anakin's key sticking points was that his love and marriage of Padme was forbidden. This is true - except in the case of our dastardly Cerean. Why is this?
The man had not only one wife - he had four. This is a 400% increase in Anakin's wives at the time of his fall.
To add some context: this is like Anakin being able to get with Padme, as well as Ahsoka Tano, Shaak Ti, and Aayla Secura. The guy had his own conehead harem!
Well, that's pretty bad - but Ki-Adi has nothing to do with Anakin's second issue, does he? He surely wouldn't have been promoted to the rank of Jedi Master without fully training a padawan, right?
Wrong.
This crazy guy got away with it, flying in the face of Jedi tradition at the time.
All he had to do was speak up at that fateful council meeting - but he didn't. He could have vouched for Anakin, or at least raised the issue of special treatment. But he didn't.
He only piped up to say something wrong (e.g. Darth Maul not a Sith, Dooku not a Sith), which leads to an ancillary issue of Mundi possibly being a Sith agent.
Exhibit A.
Exhibit B.
In summation: more than any other single individual, it is the contention of this post that Ki-Adi-Mundi is the individual mostly responsible for Anakin's fall.
