My thoughts would be that we are not inherently good or inherently evil. We have the capacity for both, and we express it as a reaction, based on our perception of how the current state of existence, is a threat to our lives or will bring us suffering.

I tend to think of good and evil as being two polarities of life. Life affirming is good, life denying is evil. Whether we affirm or deny life depends on our current perception of it, and that leads into our psychological health. In times of chaos our psychological health suffers. In that regard society can certainly play a role. I think society can increase our capacity for both good and evil, depending on the health of a society. A healthy society will affirm life. An unhealthy society will deny life. It is the individuals reaction to the unknown that leads to evil. That's my thoughts.
