Murder is basically removal. You don't want someone to be there, so you remove them. That's what it is.
I feel compelled to state, for the record, that, as a anonymous mega serial killer and lunatic internet poster myself, I realize that the whole appeal of YN/videogames/internetposting is to semi-deliberately wallow in confusion and unreality for the sake of some obscure and completely sick and wrong, yes, wrong, sense of the "sublime" or "wonder" or whatever. Nevertheless, death and murder are very different. Like, completely different. Just saying. Who knows; might be important.
Also, selectively and painstakingly hiding very tiny bits of a video game whilst mentally enacting an act of stabbing and/or shooting and/or suicide is a poor and limp-wristedly ineffectual slap fight placebo substitute for ALT-F4 -> Uninstall. Not all removal is murder. Some removal is not-murder.
