Do you want to hear my opinion with or without watching the video?

Ok will start telling you without watching the video.

Darth Vader aka Anakin Skywalker is The Chosen One, The Balance into The Force. Anakin was deceived by Palpatine not to "join forces" but to learn how to control life. Keep in mind that Anakin loved so much Amidala that he was afraid of losing her. So that isea of controlling life was seeded into his head by Palpatine to make him fall into the Dark Side.

But once he saw what he did with him with all that machinery, immediately started his own plot to kill and destroy all what Palpatine wanted: the empire.

Darth Vader is not the villain in the whole story, is the only one that can bring peace and balance. Not even Luke Skywalker couldn't do that, that's why he retreated on that lost island because he knew that could not bring the balance.

So yes, in conclusion, IT WAS AN INSIDE JOB.

Darth loved a lot Amidala and all he did was because of that love.
