From the moment those copies exist, I'm not them and they're not me. We do not share subjective experiences. If you think we're equivalent and expendable, you'd best murder me in secret and pretend it never happened. You know, like incinerating me inside a teleporter or someth... oh crap, we're going there.

Yeah, I have a few issues with that comic.

> The man was not a murderer.

This is one of a few logical leaps I can't accept. His past selves are already "dead". His future selves do not yet exist. If, for example, all my ancestors are dead and my offspring not yet conceived, how does my suicide harm them in any way? None will so much as feel the grief of losing me, but I'm supposed to feel guilty over "murdering" them? (Let's not follow up on what this would mean for topics such as abortion!)

If future and past selves are of such importance that we not murder them, how can present copies be valued any less? If destroying the original is not necessary, then that must surely be murder as well. It's worse, actually, because then it's not even hypothetical; "The Machine" would be intentionally and unnecessarily ending a life.

Why do I possess the subjective experience of me, not you, and not some other me separated by time or space? Barring notions of a soul, either those other instances are not real in some sense or else there's something phenomenologically special about each, which I can only attribute to being uniquely present at a particular point in space-time. If the teleported me is a clone, their existence ought to have nothing to do with me, thus I should not be murdered for their sake. However, if the teleported me instead can only exist as a function of my past-self ceasing to be, then that's little different than how I am from any moment to the next.

TL;DR: If it works like the movie version of "The Prestige" where one copy is murdered purely for convenience, I'm not stepping into that teleporter.
