People have always been either good or bad, or somewhere in between. Religion just takes advantage of this to advance their own agendas....

There will always be both 'good' and 'bad' people in human kind for as long mankind's backside points towards the ground.
Religions only HI-JACKED the ethics and morals of human kind to suit their own devious ends and needs.
For example,

1. Thou shalt NOT kill, Xtians have been killing others for the best part of 2,000 years, shit they've even gone as far as killing each other too,
2. Love thy neighbour as thou love thyself, well that one has worked out so well, hasn't it,
   I could go on but you get my drift, religiously based morallity is only something that the religious 'preach' to others and follow ONLY when IT suits them.

Good and evil as opposites—that is an artificial concept with no real meaning. Someone acts in a way of which I don’t approve and I give him the label of evil. It’s all about me and what I dislike.

The concept of good, in its highest context is in an entirely different category. Good pervades the universe. Reality is made out of good. Everyone is good.

I don’t like certain aspects of some religious organizations, but that is a long way from declaring religion in general to be evil. The religious impulse is man’s highest and best attribute, the source of all human creativity IMO.
