The deepest separation of labor is female and male. The female energy is associated with empathy for the child. Male energy is protecting territory.

Some combination of both these energies exist in all of us.

You can say humans have the capacity for love, and also acknowledge there are people out there who gain pleasure from power over others.

You cant say one is natural and the other is learned.

Even the people who gain pleasure in causing pain, are useful in the right situations. Hence the trope in fiction of the jailed entity being released to combat an even greater foe in a dire situation.
