I fully agree. It wasn't in the first draft, or any of the original scripts, and it isn't part of the original film. It was added into the story later and it feels it.
It's the first step Lucas took in shrinking the scope of the adventure. It was used to add shock value (and some semblance of a storyline) to ESB. For me, it was a story killer. I was very disappointed when I saw it in the theatre.
