Are Hua cheng and Johan liebert two sides of the same coin ?

Look, both had a shitty childhood and both were saved by a savior. Essentially, both of their obsessions boil down to one person only. Intellectually, both are really gifted. Hell, Hua Cheng calls himself Wu Ming (Nameless) during the Human Face Disease war arc. Johan's entire character revolves around the fact that he’s a nameless monster.

It honestly makes me wonder whether Johan could have been Tenma’s Hua Cheng if he had been saved before 511 Kinderheim. It’s tragic because Tenma is basically a "mortal" version of Xie Lian—someone who believes every life has value. But while Xie Lian’s kindness saved Hua Cheng’s soul, Tenma’s kindness accidentally gave a monster a reason to keep playing his game.

What do you guys think?
