If you dislike someone, you are focused on the wrong thing. You can't hate virtues, and you can't love faults. You can only choose which to identify a person with. Every human being is an intellectual creature, with free will, and a deep desire to be like God. It's all a matter of focus.
Parents love their children despite their faults.
Despite the fact that they make in their diapers. Despite the fact that they hit each other. Despite the fact that they are selfish. They are intelligent, full of potential, they have vitality. The reality is that every human being wants to be good and will die for it.
