Actual I'm very serious, This comes from a story my father told me. When you go through military basic training, at some point the sergeants sit everyone down and explain that murder is killing someone in an illegal fashion. Since what you will be doing on the battlefield is perfectly legal, it isn't murder. It a philosophical nicety that allows moral men to engage in combat.
Similarly, if I break into your house in the dead of night in order to harm you or take your possessions, you can kill me without warning (coldblood). And it would be completely legal and moral in the eyes of society.
Personal I believe that what completes the transport process is the individual that existed at the begining of the proess, that there would be no death of personality. However, if what materializes in the end is, in fact, a exact copy
AND you fully realize this prior to entering the chamber (you've given inform consent), then no, it would not be a legal murder. Debatably it might not even be immoral. Now I would not under those circumstantial allow myself to be transported, others might feel differently.
If you have a philosophic objection to being transported, most likely you would not be a Starfleet member.
