And if that's the case, I would need a reason for him to be left alone as a wee baby. A contagious disease? Since his genes were tampered with when he was still a fetus, could I just "invent" a new disease? It would be nice if I could find a real one, though, to make it feel more realistic.
So, can lack of physical affection and contact in your baby years lead to lack of empathy later on?
Is there a contagious baby disease which would cause the baby to be quarantained?
I have googled and did not find what I was looking for. Any help would be appreciated, as usual.
