Jacob M. Held said this quote

great literature is literature that speaks to deep, fundamental human truths and experience in a way that is relatable to the reader and that may provoke engagement or facilitate insight into these truths and experiences. If these truths and experiences are about breaches of the normal, then surely horror has a place in literature, and in facts may proffer deep engagement with the most profound aspects of our existence. Sometimes only horror can say what needs to be said.
