You can see it from both sides tbh.
Sane was clearly out of it, yet Charlotte still forces her up into a Powerbomb and put her through a table. Whether she knew she was out of it at that point, who knows. From what I remember it wasn't until after that spot that Asuka checked on Kairi. Who knows what Kairi said to Asuka, people have had their head rocked before and acted like they were fine and it wasn't until the very end of the match that Becky checked on Kairi and told her to stay out of the rest of the match.
People are stating the other three were communicating between one another but nobody knows what information was being passed. Can we blame Charlotte for it? Probably not. She might have taken a couple of liberties at the time but did she know? Maybe the Refs should have been more involved and checking on her more thoroughly.
This whole "That's what you do in Wrestling" narrative people are going with is BS though. Yes some do (if they're capable) work through injuries but the main idea is to protect the person you're working with. If she thought she was in no fit shape to continue she should have made that call and worked around the rest of the match. THAT is what you do in Wrestling.
