This only works because Subaru decided to help Emilia, otherwise she would've died anyway

Another hint is how the witches explain how if he is to do anything about Satella's current situation he needs to become a Sage, having in his power most if not all witches genes, which is still a long way to go.

Going into battle against one of the strongest characters in the series with only 2 authorities he can barely use would just get him killed fast
