Why do Christians act like people making up morals is a bad thing?

The "god" made the morals quoting a barbaric doctrine camp will fail. Their way is disadvantageous to humanity in terms of economy, and is disadvantageous in terms of psychological development. It is getting to be that is is pretty much known what circumstances it takes to produce healthy and unhealthy minds, and Christianity fails. Produces too many personality disorders, too much abuse. That is disadvantageous. Morals that are advantageous will prevail, wars will still be fought. I personally don't want to see a fundamentalist rig with a gene splicer at work, and fundamentalism is all this literalistic Christianity stuff will be in the long term, and it won't even survive save for pockets of fundamentalists unless they change their position on history, the sciences, and the social and psychological realities of human development and morality.
