Christ, what a ghoul.

"The ends justify the means" is a horrific way to run a society in any case, but of course it skips over the question of whether the means actually caused the ends, let alone were the only way to do so. Even if torture did save lives, it isn't a great justification - but then pile on top that your only evidence that it actually does work is fiction and it starts to look like the means were what you really wanted in the first place.
