Isn't that the makings of a Psychopath?
I know someone very personally who has over time perfected manipulating others
(me, for one) to the point that one moment they're compassionate and then the next they are trying to cheat you out of something. I no longer associate with this sort of toxic person anymore. Any talk of Jesus is merely pearls to swine. But I learned that you can love someone and not like them at the same time.
