Power is not an absolute, hard natural fact but is subjective and very relative. It is always given to. It is always a personal choice to subjugate and thereby willingly give someone power over you.

Resentfulness therefore can only be self-directed. An expression of self-hatred. Personal self-loathing as a result of low self-esteem. In a desperate, yet futile, attempt to save the frail and damaged ego, it is cognitively dissociated from the self.
