I am talking about a scene in which we see a dead mother and her son, who were killed by ISIS, and I want to criticize those who don't show any reactions to this crime, just watch that scene. I want to ask them indirectly: "Don't you have conscience? Why don't you show any reactions?" I thought I could use this sentence, to covey my thoughts:
Whose conscience can remain indifferent in the face of such a heartbreaking scene?
I want to focus on "conscience" in this sentence. Can we use the phrase "whose conscience" at all and does it convey what I'm trying to say?
