Naturalism cannot explain appaling wickedness

Naturalism/evolution may explain self preservation and continuity but it doesn't explain the acts of horrific brutality.

Lyrics from an unknown rock band:

I give her a rose

Then i slit her throat

Had sex with her corpse

And left a message on the wall

Something like "Helter Skelter"

I would find such acts more believable as something demonic than as a natural progression of naturalism.
