Can Endeavor make a contribution to society by just beating up bad guys? Sure. What I’m calling him out on is his desire be a role model & a source of inspiration. As well as his claims to be a changed man going forward. Symbolically laying all your past sins on a monster and then beating the hell out of it doesn’t cut it. If he’s serious about it, he needs to take ownership of his past which isn’t that easy to erase. How can he make society feel safe when his own family largely views him with fear & resentnent?
As to how do we know he viewed Todoroki as a tool for his own ends, the fact that he had no interest in being a parent to the children who did not inherit his quirk seems pretty damning. He had his wife commited to protect Todoroki? Seems kinda hypocritical considering his “training methods”. The scars they left may not be physically noticeable, but seem just as long lasting considering that Todoroki forgave his mother long ago, but still resented Endeavor. Why she married him in the first place & still hopes he will change? I admit to having no idea.
I guess the root of it all for me is “Is physical strength for it’s own sake something to aspire to?” I realize it’s just my own opinion (can’t really offer anyone else’s), but strength can make someone a hero or a bully. Pretty clear which I consider Endeavor to be. I believe Endeavor CAN change, but I’m unconvinced he’s willing to make the sacrifices to do so. Why does it need to be public? Because his recent actions show that he craves the respect & admiration of society. That means being honest about who he was as well as his aspirations. No matter how hard he tries to cover it up, it will inevitably come to light sooner or later. And if he’s been dishonest about it, it will just make his fall from grace that much harder.
