Sister Death focuses on supernatural horror within a Catholic convent, and its storytelling stays centered around the mystery and traditional horror elements. There is no significant evidence of forced representation or character identity being prioritized over skill or story development. The narrative mostly respects genre conventions and maintains character depth without resorting to checkboxes.

The film draws heavily on Catholic imagery and explores the complexities of faith, but at times it does portray religious figures and institutions in a harshly negative light. Some viewers may interpret this as undermining these traditions, though core religious themes remain present, and the depiction isn’t exclusively negative or mocking.

There’s some critical portrayal of religious authority, but the film doesn’t overtly push a singular ideological stance or consistently villainize alternative perspectives. There’s a bit of thematic uniformity, but alternative views aren't simply ridiculed or dismissed at every turn.
