But due to his personality, Janos is seen by many of the Vampire Guardian Angels as a leader who is reluctant, pessimistic, and hesitant to make major decisions. Though he finally accepts his role, he does resent it and does his best to stall on things that require his attention, such as finding a way to invade Earth from Heaven. When his girlfriend Leah commits suicide, Janos becomes even more withdrawn and indecisive, completely traumatized and still grieving over her death, unable to get over it. He tends to keep things inside, filled with self-pity, regret, and is too self-absorbed to concentrate on his role, stifling his feelings, and exploding into rare rages that last briefly. He dreads feeling any kind of emotion, and even when his father Gregory is killed later in the series, he shows no grief or emotion, other than the grief he has for Leah, as he thinks he cannot handle any more emotion of any kind.
But when he does “snap out of it” to try and lead, he is brutal, homicidal, and feels the need to make up for being seen as weak by demonstrating savagery on enemies in gory ways. (For instance, by decapitating a victim as a way of sending or emphasizing a message and drinking from the still-bleeding neck). He can also be possessive and jealous and it’s all or nothing for him. He responds by rejecting those who reject him or who do not do what he wants or when things do not go his way., which he struggles to control since he knows he needs allies and he needs the cooperation of his followers, otherwise, he fears, they might rebel.
