Anakin's mother not being freed makes no sense so it does need to be fixed.

Whether it affects his current "fall" to the dark side (which currently plays like a conscious decision) doesn't matter to me as his fall needs to be completely reworked anyway. His journey to the dark side is meant to be a seduction of power, not him being driven there by love and loss.

Anakin doesn't need to have any pre-existing resentment towards the Jedi. In fact he definitely shouldn't as it cheapens and takes impact away from his eventual fall. It's meant to be a surprise that Anakin, the perfect Jedi and perfect friend to Obi Wan ends up turning against them. It's not so much a surprise if, actually, he had plenty to dislike about them. Remember also that Ady wants to keep Anakin=Vader a secret.
