I think it makes sense in the negative sense, as things that aren't OK. What's wrong with holding oneself to a higher standard? What's wrong with saying "It'd be immoral for ME to murder?"

for one things, there are other ways of describing it, such as "personal code". For another, it renders morality pretty meaningless if someone can say "murders' OK for me".

And yet if the same neurological hardware is being engaged in order to make social moves of a similar form 'morality' still seems appropriate. Especially since morals like "people should not force their view of right and wrong on others" legitimate instances of moralizing even when the moralizer tends to take other actions which aren't consistent with the ideal. Because, as I tend to say, morals are like that.

What about "war is OK for me"?

It really gets to me that when a bunch of people gather together under some banner then it suddenly becomes moral for them to do lots of things that would never be allowed if they were acting independently: the difference between war and murder...

The only morality I want is the kind where people stop doing terrible things and then saying "they were following orders". Personal responsibility is the ONLY kind of responsibility.
