This is where the film was going.....Joe's memories of his wife were being replaced with Sarah's....and Young Joe.....even when he wanted to kill Cid.....saw that he was just a kid who needed to be loved when he saw him in the field......if you want to save that kids life you PROTECT him and you stick aorund and help raise him. Cid became the Rainmaker even without his mom getting killed by Old Joe before. Who's to say he doesn't become the Rainmaker anyway. The signs were all there on the farm pointing to young Joe finding his soul earlier in life AND being able to stop teh Rainmaker without killing him. BUt Old Joe would have to die.....
