Yoda maps the precise *mechanics* of moral collapse—not as sudden descent but as a chain reaction where each emotion breeds the next, almost chemically. The insight cuts deeper than "fear is bad": he's showing us that fear is the *entry point*, the first domino, which means we might catch ourselves at that crucial first moment rather than waiting until anger has already taken root. A person who notices themselves gripping the armrest during turbulence, or tensing at a colleague's criticism, has a choice right there—to examine what they're afraid of—before fear crystallizes into the resentment that poisons workplaces and marriages. Most moral advice addresses the endpoint (stop hating), but Yoda invites us to interrupt the sequence at its source.
