Not one of those monsters should be allowed to go to his grave without being forced to stop insulting the intelligence of the human race and to explain, in exhaustive detail, what the **** he thought he was doing, on whose behalf he did it, and what he expected to gain from it (money, opportunities to******with impunity, or both).

None if their family members should be allowed to join their relatives in hell before being forced to divulge what they knew, when they knew it, and why they didn't do the decent thing long before this (preferably killing the bastard themselves, realistically forwarding all the information they had to law enforcement).

Applying a blowtorch to his junk works wonders, if you want to get a traitor to talk.
