Fiend God
All criteria any of us uses to define if something is right or wrong are inherently not impartial, since we have never talked directly to God/Buddha/Allah.
That still doesn't answer my question. Why are you avoiding it ?
We can call an apple as "orange" but it is still an apple.
In this case it's an orange, not an apple, no matter how you want to call it.
If you redefine "murder" to mean "killing a person in a way I disagree with", then you'll find it hard to communicate with anyone who doesn't agree with you.
People call killings of other human beings as "murder" or not depending on whether they do not side with the killer or do.
Perhaps you should look up a dictionary. These tend to represent the real use of words.
