It occurred to me that Harry is confused with Hermione’s reactions (possibly Dumbledore’s) not because he is a consequentialist and she is a deontologist, but rather because he hasn’t yet realised that offending her is a consequence of being a consequentialist, and so he should include “deviates from deontological ethics; may offend friends and society” as one of the negative consequences for actions that otherwise seem right by consequentialism.
