^You know, that's a fair point. I hadn't thought of it that way. I don't buy the argument that they should've let Tuvix stay because the other two were already dead, but there is something to be said for the argument that if they'd let him stay, nobody would've died. Although one could argue that neither of them consented to the joining, so there's still an ethical question about forcing them to remain joined forever. Like I said, not a simple issue.
