They sought to convince us it was because of widespread sin

When it was just an incentive to indulge the beast within;

Who made them wield those weapons to dice a stranger's skin?

No one - it was what they offered to oblige the beast within.

The ranting versus the reason that sees the civilised win

Was just an opportunity to indulge the beast within.

The boasts of coming to get you...to kill you and your kin

Was just a brute's obeisance to oblige the beast within.

And when you hear religion used to justify murderous sin

Remember - it's just a reason indulge the beast within.
