According to Martin Luther King, justice is “love correcting that which revolts against love.”
Like God and The Devil, both sides are dependent on one another to have influence on us, the doers aka physical beings. We either love or we revolt against love. Neither is good or bad necessarily. They are simply the two sides taking opposing bets. You get to decide who wins and at what cost. And you may need to work differently to achieve different outcomes but it is always up to you.
