I've never liked the beaming into place of the people they'd picked up, by which I mean that I've always hated that aspect of it.
Well aren't you killing the version of the person you are beaming themselves into?
Every person that's ever been transported has been killed. Their body is disintegrated. The only difference between that and the disintegration chambers on Eminar 7 is the transporter then makes a copy based on the pattern and forms a replacement. It thinks it's the person it's replacing because it has their memories but it doesn't realize that person is gone.
