All they know is, it is a dangerous creature that has killed several people. The mind meld giving Spock knowledge of the creature's motives hasn't happened yet.
Okay,
great comment, this is essentially the major flaw with the entire format of the show, as it relates to ethics/morals/and the PD, et al.
Look at what you wrote: "All they know is,
it is a dangerous creature",..
and therein lies the rub, as the UFP, KIRK and Company tell us they are explorers, extending the hand of friendship in seeking out new LIFE ( not destroying that which they are threatened by, or do no comprehend), new CIVIL,... you now the speech,.. the point is KIRK and CREW, and the UFP are not in a moral position to judge anything or anyone,..
and that means they cannot MORALLY take ANY action against anything which would have any negative impact on its natural existence or evolution,.. regardless if the "Fangy Beasty" is about to eat your Geologist or not.
And that would make for a pretty depressing show,.. "Men into Space, served as a hot lunch";... this week, so-and-so gets eaten by a whatchamacallit,..
THE UFP and its forces are the INVADERS anywhere they go outside of the realm of the UFP,.. and are in no moral position to judge the slave/gangster/nazi/roman/greek/depression/computer-driven planet as "bad", nor take any action against anything they find 'wanting" or life-threatening to them,.. if they themselves are the invading outsiders,.. AND truly subscribe to all the high-minded ideals contained in their speeches about freedoms, rights, and IDIC, and so forth.
If they did, they couldn't go anywhere without an invitation, and certainly couldn't kill anything,.
,.... or as they did so often,.. disrupt the entire culture of a planet, and replace it with one more suitable to the UFP ideal and agenda,... (We can help you build schools, feed 100 where you could only feed 1, bring you teachers),... ah, indoctrination and absorption offered as "AID"
Basically it is all about PERSPECTIVES,.. Planet of the Apes handled the dilemma of cultural perspectives beautifully,... to Taylor, the Apes had taken over his world and replaced it with their simian culture,.. BUT to the Apes, "The Humans are an Infection!",.. perfect.
Since, the Enterprise's mission is to seek out (invade) areas of space not already part of the UFP corporate portfolio,.. they, regardless of the rhetoric,.. are nothing more than Imperial, Expansionist, Capitalists,... just like the good ol' USA.
and regardless of the beautiful moral/ethic/ and aesthetic values espoused in a characters' speech,.. in the end,.. if it interrupts FED BUSINESS,... WHAMM-OH!!!,.. unless the Organians or Metrons appear to nullify their aggressions while "Boldly going where no HUN has gone before".
So in point-of-fact, if SPOCK really subscribed to all that "respect all life and the rights of everything, free to be you and me speech",.. he would have resigned his post the moment KIRK gave the order to drive the Enterprise around the Fly-paper colored-cube in space.
Actually if you really compare what SPOCK is supposed to believe in, and what the UFP actually does (not what they SAY they stand for), SPOCK would not even have anything to do with the UFP,.. which really is just the I.S.S. Enterprise, with better manners, and a better line of B.S.
So the whole show is one big moral/ethical contradiction, depending on your perspective, and it is worse for SPOCK, more than anyone,.. yet,.. there he is!
Frankly, while I obviously love the show, when it comes to the conflict of what the UFP SAYS it stands for ethically & morally, and what it UFP DOES in fact and deed,.. I second the Organians utter disdain for the Earthemen.
If your going to be a space-pirate, be an HONEST ONE, don't just wear the boots!
