Ares always reemerges from the chaos. It will never go away. Athenian civilization defends itself from the forces of Ares with metis, or technology. Technology is built on science. Science is like the alchemists' uroburos, continually eating its own tail. The process of science doesn't work unless young scientists have the freedom to attack and tear down old dogmas, to engage in an ongoing Titanomachia. Science flourishes where art and free speech flourish.
There is no life without guilt anyway, at least in the Western world. I think in other civilizations it might be different but if the world is getting Westernized all over, guilt will enter through the technology and democracy and their actions. It will come side by side so there won't be anymore innocent societies in the future I think which in fact is not such a bad thing.
