> EDIT: actually, there's the brilliant Marlon Brando speech in Apocalypse Now (https://simonamooon.deviantart.com/journal/Apocalypse-Now-Ho...), where he describes bastards with empathy, people who love their families yet are able to perform the unthinkable atrocities [on their family] to win. So these folks are the opposite of psychopaths -- they do terrible things when necessary and doubtless feel the anguish of it.
Psychopathy is not the reason behind this scenario. It is in fact a polar opposite of it: in this context, doing horrible things is motivated by belief in a greater good. That is also the problem with Milgram's famous shock experiments: in his own explanation he completely ignored the part where the people willing to apply possibly lethal shocks to people where those goaded into believing it was for the greater good of mankind (that is, they were told the experiment was necessary for a better scientific understanding of the human mind).
I suspect you have very secular Western view of the world. You may want to have a look into Scott Atran's work, who dives deeper into this. This RSA lecture[0] is a fine place to start.
