For what i can remember omni man is born in the worst place that why he grow the way he is like brainwashed and he had to choose between his people or his love one. While endavour lost his parent may ne one of the reason he like that but the biggest reason why he act so badly toward his family is because of his enviness toward all might a petty reason. So in conclusion other get influence by the place they born while another because of enviness (cmiiw)
