No point in killing Han. I even doubt Harrison wants him dead now. Killing Han made sense back in ROTJ.

A death in a story isn't always meaningful, it's meaning is given by the circumstances in which it takes place. A bitter note to ROTJ made sense; killing an old man in an already dark film (they have to reinvent evil in this movie, the OT had a rather clear happy ending).

Yes, most of fans believe Harrison Ford wants Han dead in absolute terms, and that he signed on the condition of his character being killed. I think it's more sensible to think that was something Ford wanted back in 1983, and that there isn't a major reason to keep pretending it 32 years later.
