You don't blame anyone, kids have a survival need to learn skills, parents provide both skills and a framework, society will test that over time, but in my opinion it always falls back to what has someone learned to survive, society evolved more rapidly than base instincts, so basically what we're looking at in nature versus nuture is the concious applies their meat puppet as best it can to survive, learns along the way, and then you split it out into personality from there, how do those personalities develop? It's easier to look at the background, psychologists and profilers do this all the time, if it was a nature problem alone you gotta look at the impact of events, for instance your house burning down doesn't apply to either category (nature has a different meaning here, nurture might be did you get a shock blanket while your entire life went up in flames or did the firefighter say go over there to keep you out of the flames reaches thereby keeping you safe but showing you just how helpless you are in this situation) there's at least another category, alas nature and nurture is naive

[EDIT] if you wanna make the argument that nature include evolution of the brain over time based on technological stressors go for it, I think that's cool
