I might not verbalize this well and I am no longer scared of my "potential self", as such, but I do understand your concern. I cannot even play a simple board game or card game without my "aggression" entering the picture at the expense of others, and yet I can aggressively advocate necessary accommodations for myself and others without demanding or forcefully taking anything from anyone. So even though aggression does not have to automatically corrupt moral character, moral character is still required for keeping aggression on the right track...or something like that.
