@pteryx@196 fun fact about child development: Kids don't develop proper Theory of Mind until they are about 7 years old. Before the age of 7 every child is a little sociopath that is barely capable of comprehending that other people also have feelings.
Its not impossible for them to develop empathy, though it's hard. You can get those Empathy neurons firing by forcing the kid to think about other people's feelings at least once a day. So, any kid with good Empathy just has good parents.
