You don't actually think we as people have changed one iota in the intervening millennia, do you? No, it's just the moral landscape that's changed. We still love a bit of blood. It's just that the killjoy priests wagged their virgin fingers and took away our fun.
Thou hast conquered, O pale Gallilean.
The world has grown grey with thy breath;
We have drunken of things Lethean,
And fed on the fullness of death.
