I killed myself so it is a suicide. Myself is trying to kill me, it's a murder! I have no idea what I am typing about.
Murder. You kill other being with soul and body, it's called murder. this remind me about story where clone kill his original/prime self.
Murder, I consider them as different entities from myself. But if I'm killing them for the grand purpose of killing myself then it is suicide.
Murder : the unlawful premeditated killing of one human being by another. Suicide : the act of intentionally causing one's own death. So..based on your question...since the person doing it is technically still alive since the victim is a clone or antother parallel dimension being. I would say it is a murder
Probably murder. Unless your other self wanted to be killed by you in which case you'd be killing yourself intentionally. Which would probably be suicide? I—『Error: Logic Processor Over Heating 』
But, does the clone exist only because you do? If it does, what is it if you killed yourself off? Then wouldn't the clone die as a result? Or am I just talking rubbish?
Existentially suicide, but based murder, since the you that was killed is technically a variant-version of you who killed him/her, therefore another entity but of similar dimensional information. Is EMIYA killing Emiya suicide or murder? The answer to this question will answer your question.
So long as you don't die it's murder. Unless killing the clone/other dimension you will also ends your own existence.
