Can you change what you feel is right and wrong?
For example, if you feel murder is wrong, can you decide to feel that murder is morally good?
What about child abuse?
I'm not saying morals never change but I don't see that it is a conscious decision. Something outside ourselves has to be the catalyst.
So while we can judge someone's else's morals according to our own moral view we can't expect someone else to change theirs.
How beneficial then is it to complain about someone else's morality if we cannot even change our own?
