The problem is that we have not been taught how to weigh different ideas' merits and demerits. The scale is compassion with respect to how acting upon an idea affects human beings and the Earth, Herself.

A hammer can be used to build someone a house or bonk an innocent person on the head.

Seen through the lens of compassion, the good and the bad become obvious in all but the most extreme corner cases.
