Every crime has, in the moment of its perpetration, Its own avenging angel--dark misgiving, An ominous sinking at the inmost heart.
Faults of the head are punished in this world, those of the heart in another; but as most of our vices are compound, so also is their punishment.
In prisons, those things withheld from and denied to the prisoner become precisely what he wants most of all.
The thoughts of a prisoner - they're not free either. They keep returning to the same things.
