tell me, how can anything be outside of nature? are we not all God's children?
as a creative artist, i have spent the bulk of my life time outside the bounds of normalcy.
indeed that is my goal, to be different. that is what makes me good.
by your rules i should be carted off somewhere and disposed of.
maybe that is what happened to the ancestors.
once you get everybody on the same page and suppress all "deviant" behavior you will find yourself without any new or creative development.
try that for a few millenia and you got a dead society.
