I doubt you killed the good one by rolling it. You may be able to start seeing movement soon when candling, so give it a couple days and then check (was day 33 for me, but could have been sooner as I was just checking once a week). Of course just because they can move doesn't mean they will, but it's possible you'll catch it wiggling. Personally I would leave the questionable one in there until you're absolutely certain it's fully dead (as in stinky and rotting), just let them sit and keep cooking. That's all you can do at this point (and keep your chin up too).
