My opinion, b’kitzur:
There are three things that determine how a child turns out: nature, nurture, and bechirah. The first two determine how hard or easy the choices are, but it’s ultimately his or her choice. The parents are a huge part of nurture, so often, OTD can be traced to poor parenting, but it’s still not the only factor.
And popa, there are no reshaim today? Meiheicha teisi?
I’m with Spice of Life on this.
