In vain Vitaliy expected for a mercy from us for his honest serving as a guard. Conversely we used his endurance to check our new light-show system for sensual deprivation under torture.
According the criminal underworld notions it's a big fault to betray your associates. So Ilya pick himself up and prepared himself for the long and terrible pain. By any means he don't have to talk and do not violate these unwritten rules.
Oleg has no other choice but endure the pain and this is his free and conscious decision. He hopes the man in Balaclava will be merciful to him and not to flog him until he is bleeding. Anyway it's not a final torture for Oleg. Who knows how cruel his tormentor could be further...
Sometimes even the Guards need to be punished. The main purpose of such punishments is to prevent the escapes of prisoners and the collusions between guards and prisoners. At any time the guard may be in the place of a prisoner and realize all the severity of the punishments.
