The opposite of love is neither hate nor indifference. The opposite of love is fear. If love is an unconditional acceptance and draw to something or someone, then the opposite would have to be the intolerance and avoidance of something or someone, which is fear.
This is often reflected in literature and storytelling where there is a good vs evil plot. Good is almost always motivated by some form of love and they assuage the negative emotion fear with courage (the ability to resist fear). Evil is almost always motivated by fear, typically the fear of not being powerful enough, fear of loss (especially wealth or influence), and fear of Death.
Most every internal conflict a protagonist has also involves either overcoming fear, or finding love, Homer Simpson did both in The Simpson’s Movie.
