Personally don't think she would've cared, a bit fuzzy about her feelings about citizens she's supposed to protect though. But, I'm pretty sure about the dilemma the story is trying to present irrespective of how she would feel about Shura's rape/murder spree. Which is, lay grounds for animosity between the two groups (which have been going for a few chapters now) and present Shura's group as the "more evil" alternative to the readers.
I don't think it's much of a stretch though because Shura clearly has some hidden agenda that is clearly not inline with the Emperor's or with Esdese's interest, and that's what I'm mostly banking on.
