The fictitious hero Jack Bauer of the popular TV show "24" makes no apologies for having tortured individuals he knew held information that would led to capturing a terrorist(s). In real life, the decision to torture an individual for information he or she may have isn't an easy decision if you are any kind of a human being. I've asked myself how far would I go to get information out of someone who I believed had the fate of thousands or millions of people in his or her hands.
If I was sure that person had such information and millions of lives were at stake, I probably would engage in some despicable acts. At least I think so but I don't know for sure. The sight and smell of blood in a real environment makes me sick to my stomach big time. Of course torture can be justified if you cite that the person being tortured can stop it at any time by providing the desired information. You have to hope that the person being tortured does indeed know anything of use to you.
What a horrible decision to have to make and then live with. How far would you go if all this was in your hands?
There are some simpler choice in regards to self-preservation. I do know that if someone broke into my house and was coming up the stairs I would have no problem shooting that person with my trusty .38. Would I hope to kill the person for daring to break into my house?
No. I only hope to stop him or her from wreaking havoc on me or anyone else in my household. I have no qualms about doing that. I would be less than thrilled about having to shot someone but it was not my choice to break into the house and menace the occupants. I am not a good person to try and menace.
It's unfortunate in this life that choices have to be made about self-preservation but those who put us in the position of having to make a choice - a violent choice - do not give us much choice, do they?
