Nonviolence is a powerful and just weapon. Indeed, it is a weapon unique in history, which cuts without wounding and ennobles the man who wields it.

The enemy that is Envy is trigger-happy; he's pretty much a gunslinger who wields a silenced Demotivator - sent with sabotage, suicide, and suppression, he assassinates in secret, and so hopes to exterminate, to kill what was meant to motivate him - in simpler terms and less expression: he shoots the messenger.

As for what it's against - the story is against those who pervert and misuse religion, or any other kind of doctrine with a holy book and a priesthood and an apparatus of power that wields unchallengeable authority, in order to dominate and suppress human freedoms.

Be good. Do good. The devil wields no power over a good man.

A sculptor wields The chisel and the stricken marble grows To beauty.
