Armin once considered himself a burden due to his lack of self-esteem and physical strength. However he realized his intelligence is as useful even with the lack of his brawns and became confident overtime though he is still anxious if he forced to be on a spotlight specially a position of power. He is loyal to his friends and will do anything for them. He is also level headed and calculating but he is still empathetic and emotionally sensitive and he strongly believe morality is relative.
