No, it wouldn't be the same. If one of the copies dies instantly after
duplication it would be as if that copy had never been made. Consider
these example:

1. I do nothing.
2. I gather together the chemicals that would be used to make a copy
of you, then destroy them.
3. I assemble the chemicals to make a copy of you, but at a low
temperature so that its metabolism is suspended, then destroy it.
4. I allow the copy to warm up so that metabolic processes start up
for a microsecond, then destroy it.
5. I allow the copy to wake up, talk to it for a few minutes so that
it realises what's going on, then destroy it.

1 to 4 are equivalent: there is no termination of a stream of
consciousness, no aggrieved party. But 5 is murder.
