Let me go out and come back in again. We’re getting too caught up in examples. There are right things and wrong things. They’re defined based on personal opinion, which is largely based on cultural opinion, but not entirely.
There are right things to do and wrong things to do. There are right ends, and wrong ends.
Doing a wrong thing to ensure a right end is still doing a wrong thing. Doing a right thing and winding up with a wrong end still means you have to accept the wrong end.
Lying to someone is a wrong thing. But. Lying to the murderer results in a murderer still on the loose. Which is a wrong end. Telling the truth also results in a murderer still on the loose, possibly in your house, which is also a wrong end, despite being a right thing. Killing the murderer is a wrong thing to do. You have just extinguished a life. It’s something I personally dread doing. It also leads to a right end: no more murderer. (except for me.)
The point here is that none of these choices justify the end, and none of the ends justify the choices. I have to choose and accept the consequences of my choices. I will still have killed a man, even if both I and my friend live. It is a thing I have done, and I will have to accept that fact.
When talking about the ends justifying the means, we generally are considering things like torturing people to get information to stop the bomb. Yes. The bomb is stopped. But you’re still someone who tortures people. You can’t just blow that off.
Yes, lying to the Gestapo is wrong. It’s still a lie. But you have to accept that, and live with the consequences. You can not say ‘Oh, it is nothing to lie to someone, for I did it for a good cause.’ Doing a wrong thing should always be a matter of concern.
Contrawise, standing by while someone is beaten is doing a right thing, for you are not committing violence against another living person. Of course, they are being injured, which is a wrong end. And, for the rest of your life, you will have to accept that Ms. Genovese or Mr. King is in the condition they are, and it is your fault, for you could have done something about it.
It is the point of justification that I object to.
On the other hand, I should also freely admit that my family has a long history of supporting rebellion against the state, and blood is on our hands. Iranian and Irish and English and Israeli and Palestinian blood in my lifetime. Not directly, no, but we have done things that resulted in the forseeable deaths of others. And for that, we are guilty. As well as American and Iraqi blood for our parts in the American wars. And we bear our part of that, as well.
The only thing we can do about it is accept that which we have done, and keep moving. Justification of moral choices, in either direction, is a way to toss away blame, and that is as big a violation of your personal integrity as anything else I can think of.
Edit: Olent, yes, but it is not you who makes the justification or condemnation. That is the key. You still chose to perform the act. And the act, in and of itself, is right or wrong. The larger context of the act is also right or wrong, and the values for both may not be identical. But you still have performed the act.
