Giants are strong...and that is about it. Numerous stories have shown them to be kind of stupid: low-level of social organization, weak magic, simplistic battles strategies and prone to random acts of violence. Even their great king Laufey is little more than a brute. Giants like Utgard-Loki are a rare exception. Large groups may go on the rampage ever now and then, but to my knowledge they have never presented a threat to all life in the realms or try to exterminate it. Most of the time Thor can handle them on his own.
Trolls are about the same except sometimes they have developed some advance technology.
Both are dangerous and things one might wish to get rid of completely if your family was killed by them, but they are for the most part manageable.
Now, compare that to Dark Elves and giants.
What the Dark Elves lack in strength they make up for in magic and intelligence. They have intentionally tried to destroy all life in the realms several times. Unlike giants or trolls they are actually intelligent enough to comprehend all they are doing...and they do it anyway.
Then you have Fire Demons. They are unified, fanatical, powerful, and possess advanced technology. Surtur is pretty much a complete immortal as powerful as Odin, and highly intelligent. Surtur desires to set all life on fire and the fire demons are his army. When active, the Fire Demons are probably the greatest threat in all the nine realms.
Quote:And even if they can annihilate an entire race, no one has any moral ascendancy to do so. Isn't that what Loki tried to do in the first Thor movie (to annohilate the entire Jotunheim)? Didn't Thor rightfully defended the right to life, even those who are evil?
I would say there was a difference. As Movie Odin pointed out, the Jotuns were contained to Jotunheim. They were still living in the wreckage of the last war. Thor on his own slew a great many of them. There had been an uneasy peace for a thousand years. They on their own did not strike me as a threat. Only the greater trouble they could cause for an old and weak Odin. So there was no need to destroy them.
For the Dark Elves and Fire Demons, two societies that are hellbent on destroying others with no regard to any rules of war and do not appear to be able to be contained....what is the price in Light Elf, Vanir, and Aesir blood it is worth especially if they insist on starting these wars time and time again when the other realms only want to live in peace without war?
Surtur destroyed an entire GALAXY and who knows how many races. He is more than willing to destroy the nine realms. He only needs to succeed once now that the Ragnarok cycle is broken. He is determined to do so. What is the price of that threat hanging over the heads of the realms?
In the first Thor film yes Thor did stop Loki. But against the more dangerous Dark Elves Bor was credited with their extinction. Thor finished off the race. I don't recall anybody being torn up over it.
Each one of whom are far more dangerous than all the dark elves and fire demons combined.
Sure, Galactus is not technically "evil" as he is just surviving by killing billions by consuming planets...but at the same time, he doesn't really care whether he destroys a race or not. He thinks everone is beneath his concern, and he will just consume an inhabited world over an uninhabited one if it meant that it will satisfy his hunger more. He is an amoral being who devastates entire solar systems, galaxies, thousands or millions of worlds in his mad attempt to satiate his never ending hunger. And yet Reed Richards saved his life.
Celestials judge worlds whether they live or die. They experiment on countless races just because. They can wipe out worlds with a mere gesture. Should we exterminate all of them as well?
Thanos has actually killed half the population of the universe just to please his love Death. He continually aspire absolute power in order to...
Ummmm....i don't know his reasonings now...but it used to be to serve countless souls to his love Death...now, i reckon, just for abdolute power's sake. He should be put down like the dog he is.
Not all Elves are warriors. Not all of them kill. Killing is only justified for self-defense. If you exterminate an entire race for the actions of Malekith and his warriors, that is genocide. That's why Thor stopped Loki in the first movie. Not because of that truce between Asgard and Jotunheim. Killing an entire race is wrong.
As for the fire Demons, Surtur is the most dangerous by far, and is far more powerful than all the other fire demons combined....should we kill all pesky fire demons just because Surtur is a raging multiversal arsonist? Odin could have killed Surtur, but always choose to imprison him...because killing one who is already down is murder, and wrong.
