What you just did was explain the value of Situational Ethics.
Everything seems to “depend on the situation” because “it’s not that simple”.
No thanks.
But the situation is important.
If you kill me because you don’t like my face it’s murder on your part.
If you kill me because I’m trying to kill you because I don’t like your face it’s not murder but justifiable homicide.
Either way I’m dead, but whether it’s murder or justifiable homicide depends on the situation in which I got dead.
