For what it's worth, Dick Cheney is human scum. He can only be admired in the same way as a Xenomorph or a shark. Perfect at what it does, but nothing to emulate. He helped get us into a moronic war based on lies. The blood of every man, woman and child who died during that war is on his hands and the hands of every politician who didn't try to stop it.
Also I also saw Zero Dark Thirty. They clearly showed that torture doesn't get results. A traditional interrogation did. Do you understand what that means? One worked, one didn't. That doesn't mean both work. It's simple, binary, a cat could understand it.
Also I recommend you check out the Governor on Walking Dead. Seems like your kind of hero. He does what needs to be done in order to survive. You kill or you die.
