Does anyone know why Harrison Ford wanted Han Solo dead?

Harrison thought it would be best for Han to be killed. He liked the idea of someone who started out to be about himself to give up his life for someone else. I have scene the new move so I won't comment if Han dies or not. It is a good move though

I haven't seen the movie but I think it's because he is getting old and what if he died and Han Solo hadn't died. They would have to make it that he disappeared and had died. We just wouldn't know how he died and we wouldn't see it happen.
