This is an interesting construction. It would seem to suggest, by context, that Claudius thinks no church should be excluded from being on the list of places a person can murder. BUT – if this sentence stood on its own, it would seem to say something else entirely.
Murder is the active word here, and the subject. Without context, he would seem to be at first agreeing with Laertes, because he says “indeed.” But murder is doing the sanctuarizing. Almost as if a place could be consecrated by murder, by blood.
Like, no place should be sanctified by blood. No place should be turned into a sanctuary BY murder – when he would seem to really be saying – no place should be a sanctuary from murder. But it’s hard to see that exactly in the sentence. It’s very curious.
But I suppose religion has been known to be quite bloody and not exactly free from murder…so I suppose there might be some hypocrisy to point at with a sentence like this.
