The Problem of Evil compels a decision really, that's what this comes down to. A lot of things, you can say, well, you know, they were raised in a bad environment, abused by somebody, they're in poverty, hooked on drugs, etc, etc, that's why they do bad stuff.
This?
This is conscious, willful, deliberate embrace of Evil with a capital E.
In the face of this moral relativism hits a wall it cannot pass.
