According to the original author the brainwash thing won't be mentioned anymore. Unless he meets his mother again, something that hasn't happen yet in the original site. Even though he doesn't hurt women you will see how he will hurt them mentally throughout the fanfic. And is definitely quite a sight.
In chapter 11 it said that because of what his father did to him, Izuku beat*d him so bad that he sent him to a hospital and because of that both his father and mother had to run away from him. They saw his potential and determined that he was a menace. He already got his vengeance man against his father at least. They will appear once again in the future if that's what you are asking.
