[Star Wars] How much did the betrayal of Ahsoka by the council contribute to Anakin's fall to the dark side?

Well she was a rock of his, someone that understood many of his plights. She abandoned him at his darkest hours. 

According to Legends Jedi Masters are permitted access to holocrons that can teach more esoteric powers of the force. Nigh unnatural. Preserving life, for example.

Had Ahsoka stayed in the Jedi Order, she'd have been knighted. And Anakin promoted to master. Her abandonment prevented this.


Her leaving is key to his downfall.
