In "Beginning of the End", he takes his cause, and the lives of his underlings seriously, rejecting Cinder Fall's initial offer of an alliance, citing the unnecessary risk of dying for a human cause. It is also hinted that he dislikes Huntsmen, sardonically stating she could have gone to one who strayed from their "righteous path". However, after Cinder arrives a second time, this time with an offer of Dust and Lien as well as a death threat, Adam begrudgingly accepts her terms. Furthermore, in "The Next Step", Salem states that Adam has proven to be loyal to her cause.

In "Heroes and Monsters", Adam's ruthless personality comes to light. He is revealed to be an embittered, sadistic and vengeful man, willing to cut down any opposition towards his twisted ideas of justice being dispensed upon humanity. He takes great pleasure in tormenting Blake, taunting her by calling her "darling" or "my love" and ultimately promising to destroy everything she loves as punishment for her betrayal of the White Fang and, by extension, him. He exhibits extremely possessive, violent behavior.
