There have been multiple studies on the descendants of Holocaust survivors looking at exactly this btw.

I would think surviving absolute horror would shape the education one would give to their children. Why is it necessarily epigenetic?

Maybe not necessarily; it might turn out to be both with a little more research done? Out of many psychological phenomena, this seems like it could actually be quite research-able.
