Cheney and now George W. Bush have claimed that torturing saved lives. However, they don't have anyone backing them up on it. In fact, everyone in a position to do it, hasn't but has rather said that torture wasn't necessary and didn't work but rather aided the enemy — that all the good information was obtained before the torture commenced.
The truth though is that it doesn't even matter if it worked as Bush and Cheney claim in their boldfaced lies. It was illegal and for good (better) reason.
Stooping to evil to save lives ends up meaning saving evil with evil if those saved agree with the worldly imperial project and torture, which so many neoconservative Republicans and self-styled conservative Christians do.
