Every hear of the 'dark night of the soul'? The soul is 'whole' and contains both dark and light.

"Perhaps, but if you break the religious leash on the dark side, you may find that it is relatively easily controlled if not completely eliminated. The first step is to realize that almost all people are good people, most importantly yourself. That way when the religious guru tries to help you control the dark side, you may properly ask what dark side? The guru will say the dark side we all have, and you can properly say speak for yourself. Depending on the religion the guru will say all are sinners, or all have the yin and the yang, and you have every right to use the tiresome atheist mantra: Prove it. The guru is making a positive assertion and the default is that it is false. Pointing to the occasional bad guy doesn't cut it. You may properly ask to show your dark side, hesh did say all after all.
A person starts with total control over herm soul. It has no sides or points. Your parents and family will normally help you shape it into the benevolent and beneficent soul that is your birthright. Don't sell it to the devil guru who will inevitably shape it to herm needs, not yours."
The most pernicious result of ceding the soul to religions is that they then get to define it any way they want to, and you can bet your tithe that it won't be for the benefit of the parishioners. It will always have the dark side that God or the guru will have to help you manage. And managing it means making you worry about it all the time as if it were really a part of the natural soul. It isn't.
If humans were evolved with a dark side to the soul they would have joined the rest of the hominids in extinction. Mom and the other caregivers including of course Fulghum's Kindergarten teacher, will guide the development of the soul in socially integrative, benign, empathetic, loving ways. Unfortunately the social milieu historically has included religious indoctrination which includes hijacking the soul for the benefit of the shaman.
It is critical that when one shucks ones milk church, one pulls one's soul out and shucks the dark side that was indoctrinated right along with the need for the God of the milk church.
