While I believe I don't have the right to sacrifice/hurt others, that doesn't mean that I wouldn't do it if specific circumstances were met. If I really, really couldn't find another way. no matter how hard I try, and if the stakes are high enough...I guess I would do that. Altough I probably wouldn't be able to live with myself after that.
Whereas the hypotherical guy in question wouldn't flinch. If that is not a crucial difference, I don't know what it.
You seem to be confused. Either you think the ends justify the means or you don't. Any sort of compromise involves some sort of slippery slope.
It's not that simple. I think TrashMan is trying to say (correct if I'm wrong) that since he has never been in that kind of situation where that kind of decision would be required, he can't know what he would actually choose in that kind of situation regardless of what his present ethics say would be the right thing, which is actually a very valid point - it's easy to stay on an ethical high horse before having to make a decision like that. In reality, people put in those situations tend to either freeze or make fast decisions that result in some kind of action and reaction, but in general the survival rate of the deciders is better than that of freezers, whether or not the results of those decisions end up being positive or negative.
As the golden rule of infantry says: If you do not know what to do, attack. If you don't know how to attack, flank them. If you don't know from which direction, flank to the left. Anything tends to be better than nothing...
Not to mention situations where loss of life is unavoidable but there's a choise between lesser and greater havoc, and fast decisions are required to limit consequences:
Also, like you said, if you want to follow on your earlier post
I don't think I have the right to sacrifice other people for some goal, regardless how good that goal may be.
you have no choice but not doing anything. Any sort of actions against people just because of their thought patterns could be considered some sort of sacrifice for some sort of goal.
Actually, the better formulation of this principle is never to use people as means to an end
only. Or in other (and more) words,
Categorical imperative. It's pretty interesting reading...
According to categorical imperative, people have so called "perfect duty" not to act so that one could not accept as universally acceptable behaviour. Similarly, we have "imperfect duty" to
only act so that it could be universally acceptable.
Obviously, in some hypothetical as well as real life occasions, people sometimes need to make decisions that invariably lead to someone getting hurt or killed. Inaction could result in the death of all involved, while action of any kind might save some people yet doom others. The most common and usually fastest decision is driven by self-preservance and can be ethically defended by the perfect duty - if no one cared about themselves and let themselves die, it leads to logical contradiction and would eventually end in the death of our species, which is undesireable. On the other hand, it contradicts the imperfect duty, because when you start sacrificing people to ensure your own survival, that would eventually at extreme case lead to just you being alive, which is just as undesireable as everyone dying. In cases like this, it is in fact utilitarian ethics that actually work better than Kantian ethics, in the sense that they allow one to make
some kind of decision. Inaction, in most life-and-death situations, tends to make everything go south - the only worse thing is to panic (though again there are exceptions where panicking is the
exact right thing to do).
It's also important to remember that in Kantianism, the underlying maxims in any action define the moral/ethical value of it, not just the nature of the action itself or the consequences of the action.
