All For One just played a mind game twisted on so many levels that readers probably had to check to make sure they were reading Joker.
One of the greatest Joker stories of all time is The Killing Joke. That famous series sees Joker trying to prove that all it takes is one bad day for anyone to become as messed up as him. The Clown Prince of Crime endeavors to prove his hypothesis by subjecting Police Commissioner James Gordon to a series of truly horrific and maniacal perpetrated misdeeds. First, Joker paralyzes and assaults Gordon's daughter, Barbara. Next, he captures and then exposes Gordon to a carnival show of horrors in the most humiliating and terrifying way during which time he shares images of his daughter's assault for Gordon to behold. As truly disturbed as Joker's actions are though, they don't hold a candle to the main villain of My Hero Academia, All For One.
At the end of chapter 316 of My Hero Academia, All For One's actions prove that he knew that Lady Nagant, the woman whom Lady Nagant and Deku that she had willingly chosen to follow him, instead of her being coerced into it.
In other words, All For One could have easily found a way to apprehend Deku, which would have brought him one step closer to victory. But, instead, he weaved a deceptive plot that was contingent on the person who could have played a major role in his success betraying him, all so he could sully her redemption.
In the case of Joker, Gordon is able to disprove the psychopathic jester that everyone and anyone could become as messed up as him over the course of one fateful day if the right variables were met, but it comes at a terrible price. The mental anguish that he sustained in The Killing Joke would go onAll For One just hopes to convey the message that he possesses the power to negate the sanctity of amazing grace.
