There's been much debate about whether the portrayal of Optimus in ROTF was too brute and 'un-Prime-like'. I'm interested in what motives, beliefs and thoughts govern movie Prime's actions, so let's discuss it. I think there have been two obvious main aims that Optimus has strived for from the 1st to the current 2nd movie: 1) Stopping the Decepticons from their goals of universal conquest. 2) Protecting Earth and its human inhabitants from the Decepticons. Perhaps the 2nd aim is the more outstanding one. Why? Why is protecting the human race so important to Optimus? From his 1st movie description of the human race as "a young species" that "has much to learn" but that he has "seen goodness" in to his opening dialogue in ROTF where he describes the human race as "capable of great compassion, but also of war", Optimus obviously draws parallels and comparisons between his Cybertronian race and the human race. This i believe is one of the big reasons why Optimus feels compelled to protect the human race: because we are very much alike to his own, capable of compassion, but also of war. Optimus' desire to defend the human race extends even to protecting us from our own capacity for war as he indicates in his talk with Galloway at NEST HQs. Galloway reveals that the Autobots had agreed to "share their intel" with Nest, "but not their advancements in technology", to which Optimus responds firmly that he has "witnessed" the "human capacity for war" and that "it would absolutely do more harm than good". Galloway argues back: "but who are you to judge for us?". Optimus seems to be all too aware of the human ability for good and evil. Though he believes humans to be worthy of protection from his Decepticon enemies, he is not so naive and ignorant to believe that humans are completely innocent creatures either. At the end of his talk with Galloway, Optimus agrees that he and the Autobots would leave Earth peacefully if requested by human leaders, stating "freedom is your right". This is yet another display of Optimus' belief that "Freedom is the right of all sentient beings"; even though he warns Galloway about the unwiseness of such a decision, he ultimately champions his core belief in freedom. He allows humans the freedom to choose their own fates, make their own decisions which he will respect. Now moving on to Optimus' stance on the state and future of his dying race. We assumed from the 1st movie that with the Allspark gone the Cybertronian race lost its only source of life. After fighting a never-ending war on their homeworld of Cybertron, Optimus eventually was willing to sacrifice the only known source of life for his race, in the hopes of keeping it from Decepticon hands and putting an end to their war. Then in ROTF, this stance of Optimus' is once again emphasized when he defies Megatron's "Isn't the future of our race worth the cost of one human life?" with "You'll never stop at one!". Optimus by now knows Megatron only too well and knows that if he allows him the means to create more Cybertronian life, other worlds and life will suffer under an empowered Decepticon threat. All this means that ultimately, not allowing the Decepticons victory and stopping their war is more important to Optimus than the survival of the Cybertronian race. This is a tough dilemna for Optimus as a leader of his people; in the end, it seems he would rather sacrifice his race than allow his enemies to spread their war to other worlds. He essentially chooses extinction over a warring existence, sacrifice and death over unjust life. In his mind, Optimus perhaps blames Megatron and the Decepticons for starting and bringing war to their once peaceful world of Cybertron, and he is determined that they cannot be allowed to spread their war across the universe to other worlds. This justifies his and the other Earth-bound Autobots' mission in ROTF to hunt down and eliminate Decepticons on Earth. Optimus cannot allow Decepticons to grow in strength and nos. on Earth and thus threaten it and the humans. Personally, i feel this Optimus Prime has alot of depth to him by the difficult decisions he has made that forseeably condemns his race to a dying future and the way he has likened our race to his own and placed new hope in humans and Earth as a new home for his Autobots (since Cybertron seems to be a dead world now). So what do the rest of you feel about movie Prime's character evidenced from all of the above? How much does movie Prime's morals and goals really deviate from previous incarnations? I'd like to hear other thoughts on movie Prime's morals, beliefs, motivations, stance and general philosophy.
