It reminds me somewhat of a scene from the Berserk Abridged fan-series where Guts tries to deal with his parental issues by killing a young boy with a similar background.

He is shocked to find that this makes his parental issues worse.

Somehow I don't think 'completing his training' will make Kylo Ren feel better about this.
