I think there is also a strong instinct not to harm or kill our peers which only by exception can be over-ruled - by emotional trauma or threat. We can't detach destructive tendencies from dynamic cultural circumstances.

At the same time moral ideas communicated in these modern times are not assured to improve. Here is hoping they do.
