"Necessary Sacrifice" showed us that Corsac and Fennec were using Adam as a figurehead for the more radical white fang faction, and that they can and will replace him if he becomes hard to control. Adam was possibly one of the youngest members of the white fang when he faced whatever tragedy that led to his hatred of humans. At some point after this tragedy, members of the Albains cult approached him and filled him with their philosophical view on how Faunus were the superior species of Remnant, and that humans should be put to death for their cruelty. This brainwashing, combined with his mental ilness, led to Adam becoming the monster we all know and fear. True monsters aren't born, they're forged.
