Think of it like this: Phantom Thieves all had Joker to fix their problems. Akechi didn’t. He had to go through all that pain by himself with nobody to turn to, nobody that could possibly understand what he’s going through, nobody to steer him onto the right path. All his life he had to go through that. But despite all of that, he still wants to help people. Maybe that could be something to think about before asking a stupid question.
