In general I offer my demons a cup of tea and a civilised chat before I lock them away again. It's not their fault, poor things, and I suppose those frozen outlying circles of hell that Dante described aren't an especially nice place.
Sooner or later they will be redeemed, no doubt: but not by me.

Demons: I shouldn't be nasty to them, but can't help myself. Not very PC of me really.
