When I was at a UC in my late teens it was all about "nurture"....as a parent I took it seriously as well...as a grandmother I discovered 22 years ago that "nature" had been thoroughly underrated...and I have a mess of look alike and act alike grandkids to prove it.

A very very wise nun instructor said that we are not as instinctual as Freud argued nor as free as Thomas posited but on an ever moving continuum....and that was BEFORE the human genome and recent neuroscience...

I really don't have any answers just a whole lot of questions and some very mixed data....but one thing I suspect is true is that none of this is even remotely simple nor has institutional Church even begun to factor in any of it...which they most definitely should do...if they are to speak with any degree of relevance about issues/morality/responsibility in the 21st century...
