it is an interesting question, i like most of all that you added specification that they ARE completely you as of the moment of cloning, not blank slates but have all your memories and experiences, and likely would be indistinguishable from you, hell they probably believe just as i would that 'i am the real one'
i'd honestly be rather afraid with another 'me' running around, especially when 'technically' either i or them could 'get away' with anything and just blame it on the other... it brings about a grave morality dilemma, the fact that there even 'is' an 'other' me would automatically stimulate a competition to strive proving either my own or their validity as the original...
i've been doing a lot of this in philosophy class lately actually, thought exercises like this, and i remember some of the stuff i learned in psych... by those sciences we as humans in our efforts to identify ourselves as 'the original' MUST destroy the impostor to validate our argument permanently... nature, our psyche, and entire being would demand it... suppose i'd be more weirded out by people saying 'no we mustnt' for some innane reason as 'morality'...
but suppose that is the kicker... i know how i think, i know how i am... i can be bother horribly cruel or the kindest of saints, suppose its only a matter of which identity i take and accept...
suppose another thing that would make this 'moot' is that the moment we are 'separate' we start having 'separate' experiences and then become two different people... then its no longer an arguement about killing a clone but someone disturbingly 'like' me but not 'me' as they are separate from me and out of my will...
i forsee a dark room, a table with a lamp, a knife pointing one way, a gun pointing the other on the table while me and myself sit across from each other and have a rather surreal 'conversation'... how it will end... who knows... i'm very territorial therefore it is likely we both would be... no one would leave that room the 'same' as they went in... one would lose everything and need to craft a new identity, the other the 'victory' who gets to keep the spoils of what is familiar...
edit: you need an 'i don't know' option for the true neutral
