Jellico is a better captain than Picard who is a textbook example for good leadership? That's beyond ridiculous but it is always interesting to see how authoritarian personalites tick.
You suggest in the case of Jellico that officers have to always follow their superiors, even when they give orders just for the sake of giving orders. You also argue for the "deconstruction of Starfleet values" in the case of VOY.
Trek is not about "follow the leader and ignore your rules, ethics and principles". It isn't a fascist (or shall I say monarchist) but rather a liberal franchise which especially in TNG frequently dealt with wrong authority, e.g. Jellico, Satie, Dougherty or the Picard impostor from Allegiance.
