[Star Wars] How would Anakin have turned out if Qui-gon hadn't been killed and had trained the boy?
gpt
A consistent psychological problem that appears with Anakin is fear of loss. 

This fear of loss could be mitigated by Faith in the Force. Anakin appears to never truly develop this faith, seeing the Force only as a power controlled, like electricity and gravity.

Qui-Gon was a follower of the Living Force school of Study, bending Jedi rules to better feel the Force.

I believe that the relationship between Qui-Gon and Anakin, which was very paternal from the beginning, would be extremely beneficial to Anakin. 

First by removing an element of Loss that Anakin experienced, I.e. the immediate loss of the only Father-Figure he had. But also helping Anakin through the hard life of the Jedi.

The Jedi were a Monastic Military Order, as such it was strict with discipline and meditation. Anakin who was too old for training didn’t learn how to properly control his emotions, he fell into the common trap of repression. You are NOT supposed to repress your emotions. Turning numb only causes problems to fester and turn into anger.

Qui-Gon should be able to properly work Anakin through this repression and help him address his fears.
