Torture versus collateral damage; the bigger evil?

[carl]

I've always wanted to ask guys like Mr. Harris this.

'Ok Mr. Harris, we know that devil incarnate bad guy knows where the ticking bomb is. Unfortunately we can't get at him to use our sure fire enhanced interrogation techniques that would be applied by highly trained career professional torturers under closely supervised conditions. But we can get to his wife and children. In fact we have them.

Now Mr. Harris you must know that if that bomb goes off many many innocents, women and children, will be maimed and killed. They will suffer immensely as will their surviving relations. Is it really so bad Mr. Harris if we were to send an ear of his oldest child to devil incarnate bad guy with the message that this is only the beginning if he doesn't tell us what we want to know? Wouldn't inflicting suffering on those people be worth all the lives we would save?'

I wonder how he would answer.
