So what crime did Tuvix commit to warrant the cestation of his existance?.
But his existence was not ended...that's the point....why do people keep missing that part....he continues to exist in Tuvok and Neelix
The only thing that was ended was a personality (one which was entirely dependent upon the existence of Tuvok and Neelix)....and ending that cannot be defined as murder otherwise, Janeway forcing Borg Seven to abandon her Borg personality in favour of her human personality would also be classed as murder....Samantha Wildman allowing Naomi to grow up and develop an adult personality that is different to her current personality would be classed as murder
Murder has not taken place....just a very weird transporter accident that brought up some very interesting questions about the nature of sentience, existence, consciousness and individuality
One of the best Trek episodes ever
