General Deveraux was the most evil character
Know why?
1.- He invited the situation (capturing a terrorist mastermind is one thing, kidnapping him in a black hole without some sort of trial like Gitmo is ILLEGAL). The simple principle of escalation (you HAVE to expect a response).
2.- He pretty much WANTED the situation (at no point is he surprised or pondering about anything as if evrythig is fitting into his plan).
3.- He BS his way into the top post (his speech about not using the army is clear example of "covering his ass" since he can now say "Hey, don't blame me for the crap I did since I TOLD YOU SO".
4.- While a piss-poor terrorist can blow up dozens, a uy like him in his position can kill thousands.
