My point is that "sociopathic" behavior sometimes develops because others have behaved pro-society.
Like everneo is saying above, there are different causes for "sociopathic" behavior, even though on the surface they might look the same.
There are people who are born with sociopathic predispositions.
And then there are people who are made into sociopaths.
We can't put the same label on all "sociopaths", nor is society free of the responsibility for causing some people to become "sociopaths".
There are sociopaths who pretend to be working on the side of society. Society itself can be sociopathic, which is pretty much suicidal.
A "society" can decide to kill and can justify the killing to itself.
