Adam appeared very egotistical and unsympathetic. As the leader of his Exorcist army, he took his stance as the Exorcists' head figure very seriously, sending antagonistic threats towards demons and anyone for standing in their way or whoever disobeyed his command, as he did so with Vaggie for refusing to kill a Sinner, cutting her wings, and leaving her in Hell. He also displayed traits of extreme narcissism and chauvinism, believing himself the perfect man due to being the first.
