In theory you shouldn't allow torture, but in practice it might not be that easy to maintain your views.

If I think of a situation where my loved ones were held captive and the only way to save their lives would be to beat one of the captors I wouldn't hesitate one moment. I'm not saying its right, but that's what I'd do.

A bit similar situation:

If you knew for sure that by killing one man you could save the lives of 100 men, would you do it?
