I think we can say it was a useful plug for explaining the inherently predatory nature and behavior of humanity as it relates to Darwinian game theory and telling people that yes, under most circumstances, we have evil in us because evil is oriented to winning zero-sum / negative-sum games hence there's a fitness pressure, especially when there's intense human v. human competition for resources and status, for us to get more evil so we can climb the hierarchy more, throw more people down the ladder, have more interest from the opposite sex, have more kids, and displace the people who weren't as ruthless and didn't gain status.
If you have to explain to a community, that you're in charge of seeing to the future and longevity of, the problem of evil then you have to think about rigging explanations that help people understand the problem even if there's no materialist theory of evil at that given point. The future cohesiveness of your community and their ability to maintain cohesiveness over zero-sum / negative sum games partially depends on a swift handling of that. Without cohesiveness your community disappears.
