Some emotions are broadly considered undesirable, but it's unclear whether they're inherently unethical to feel or simply uncomfortable, natural human responses that deserve less judgment. This unresolved question touches on the ethics of emotion itself.

People change considerably over time, and it's unclear whether commitments made at an earlier, less informed stage of life should remain fully binding later on. This unresolved tension appears in debates over long-term vows, career paths, and personal commitments.

Ancient philosophers debated whether a truly virtuous life necessarily conflicts with self-interest or whether they ultimately align, and modern philosophy hasn't settled the question either. This affects how we understand the relationship between ethics and personal flourishing.
