I absolutely wouldn't kill my clone! I mean, assuming he passes all the requisite checks. I don't really trust or open up to people, but not really an issue with an experience clone, I'm sure we'd become fast friends. That or it'd just be too weird and we'd establish two different lives to avoid that, but kill my clone? Sheesh, besides ethical issues about murder, self-murder making it even more messed up, it's just not necessary with me. I prefer diplomacy first, argument second, and violence almost never, and only against people who deserve it.
Granted, I don't have kids or a significant other, but if I did, we either wouldn't disclose the clone thing or we'd claim that we didn't know which, if either of us, was the original, just to avoid that creating problems or anyone feeling left out - my clone or I wouldn't have much of an issue sharing a life, or establishing a second life for the clone, either to be separate or shared between us. We'd work things out, rather than it turning into a you/me vs. you/me sort of thing.
