Is Sarang a complete idiot?

Yes, he is. Your copy is a separate being. It's an exact copy, yes, but it's not the original you. Well, it IS "you" but they are physically separate entities.

Killing or not killing your original self will have zero effect on the copy.

P.S. The brain scan and copying process in soma is very much like what happens in "The 6th Day" movie.
