I do think that they are products of their environment, I say this because of people who are descended from SS soldiers.
I don't believe many people were born psychopaths. I am curious though.
I am primarily concerned with leaders doing psychotic things.
I worry that I might be descended from a member of the SS, since as previously stated my father was adopted.
It's not like their creed was evil, loyalty is good, it helps make civilization, it can be abused of course. It should be discerning and not fanatic though.
