In conclusion.
Although the idea of learning to let go is basically right, I think the Jedi have implemented it too radically. Instead of forbidding attachment (as intended by Lucas),I think they should have taught how to control it, allowing people to express the fear of loss in a balanced way. Their wrong teachings played a very important role in Anakin’s fall, because they didn’t allow him to handle his emotions in a healthy and human way (because I repeat, suppressing the fear of loss is neither healthy nor human). Then, if we also add Anakin’s manipulation by Palpatine, who taught Anakin to handle his negative feelings in the wrong way, then we have Darth Vader as a result. Darth Vader is simply what you obtain when you mix up a person with already existing emotional problems, the wrong teachings of the Jedi that doesn’t allow this emotional problems to be solved correctly, and finally Palpatine’s willingness to take advantage of all the above to carry out his own agenda.

I 100% agree!
