This question has often been asked, but the answer is simple and clear. The answer is that the ruling ideology of the world is Evil - and evil has no positive definition.
The name of Evil does not derive from what it wants but from what it opposes; and that is Good, which is God and divine creation.
Evil is not something you Are, but a cause you serve. It is not a specific group, but one side in a Spiritual war; a war where each individual can and must choose which side he supports. (No abstention is possible.)
The problem with giving a name to Evil thus understood is that it constitutes the entirety of world and national governments (all parties), the mass media, and the (cross-linked) bureaucracies of all major social institutions (including 'Christian' churches).
For most people, Evil thus understood also includes almost every person they know.
So the problem of naming Evil is the problem of acknowledging its overwhelming prevalence and power.
