The answer is no. Spending one third of the film on his rescue just to kill him would have been beyond stupid.
This and more! I understand the thought to kill one of the main three, JK almost did it to Ron in Harry Potter, but I think ROTJ has its own issues and killing Han would ultimately be more of a band-aid to the real problem which is that a lot of Endor stuff is boring. It’s not death you seek, it’s depth!
