"According to my values, murder is killing of a person other than in defense or an accident. "

I believe that is how you feel but I don't go by feelings or make up my own definitions of words, I use the dictionary and what every dictionary says is that murder is the unlawful killing of a person. Lawful killings are not murder, by definition, even if you feel like they are. You can have your own values but does that also mean you get to redefine words however you like?
