I find that evil is when you are entirely self-serving.
the opposite of that is when you offer your aid and intent to others.
one is self-directed, concentrating power unto oneself (at all costs)
the other is radiant, and aims to distribute the strength and power (all benefit from the actions).
rarely does a person fall into either category entirely; we are an admixture of these two motives.
what is clear, is that choices are open to us at every moment of the day to choose which way we want to go with things. The default is a neutral unemotional apathy
so choose your way!
