I have two kids who are so different in temperament that's it's just not funny. Considering they are only separated by 2 years, one has to assume their upbringings were pretty similar, so that leaves genetics as the primary driver. If you take this to its logical extreme, you would have to find people whose genetic combination is such that no amount of nurture and 'good' upbringing could ever compensate.

So yes, I believe there are some people out there who are just fundamentally at odds with what society would define as a 'good person', from the outset. Horrible thought (Divergent, anyone?!) but they're sort of buggered from the start aren't they...

I feel like I've read a book that talked about reasons humans seem to have more diverse personalities amongst a sibling group compared to most animals. I'm afraid I can't remember what the book was or what it's conclusions were, though 🙁

I'm pretty sure there are studies that look at this though, in particular with twins, especially identical twins, as part of that old nature vs nurture debate.

I have 3 boys, they are all very different; the oldest is very academic, but he has issues relating to people; the middle one is kind and thoughtful, very imaginative and funny; the youngest is very physical, loves to play and push and just be active.

All of them are similar is a bunch of ways; but there are differences and I have to assume there is a genetic component.
