[The Fly 1986] Was the Original Brundle dead from the moment he teleported himself?

I know this is a big problem with teleporters in Science Fiction, but The Fly seems to be more on the side of it actually being a definite case of it being a case of "Original version destroyed, copy replicated on other side".

For example, when Brundle replicated the steak, it tastes artificial. 

It is the computer's version of a steak. 

Sure, Brundle teaches it to be "crazy about the flesh", and the steak winds up tasting like steak, but that's like comparing a dot-matrix printer to a modern printer. It's still not the original.

If I were to send you a fax, and it shredded the original up, and destroyed it completely to the atom, it would appear that the paper had been recreated on the other side, but it was destroyed. It is a copy, not the original.

It's still tied up with the definition of self that all teleporters have.  Are you the physical matter that makes up your body?  Are you the pattern that matter is arranged in?  Are you the collection of memories you hold?  

I don't recall that Brundle tried to tackle those questions, he just seemed pretty sure that he'd still be him on the other side.
