I only consider the taken and hive truely evil. The rest not so. The fallen want their God back and will do anything to get it, but they took the wrong approach and thought they should kill us, cabal just want resources or maybe flee from oryx or study the traveller in secret, and the vex (now this is just my theory, not nessacarily true) only began to worship the darkness to try and defeat oryx, they are a defense mechanism from Charlemagne who made them and became their first mind to defend humanity (notice how the vex never attacked us until provoked, and still don't attack earth, plus they worship Rasputin and seem to know when he's going to strike, also "an evil so dark it despises other evil, maybe because that was their original function, destroy any evil attacking humanity, because oryx is darker), but due to their ability to time travel, all of them worshiped the darkness, and became a sort of evil, though a part of Charlemagne still exists and controls them to a certain extent.

Earth is pretty much under Fallen occupation. If this game was rated M there would be more details on the genocide the Fallen committed.

What if in Destiny 2 Bungie takes a Halo 2 approach and makes The Fallen our allies? Like combine our efforts to fight off The Darkness. We already have Variks, so they wouldn't be too foreign to us.

They were once very proud and honourable creatures. Every House lived in harmony. There was no ether scarce. No servitors or even dregs. They were Eliksni. Great and powerful and all around noble. When the Traveler left....well the one Kell that pretty much was their idol Chelchis stayed to fight and died. They lost their god. Their most idolized Kell was dead. They fell into savage ways. Their life force ether was drying up. They discovered or created the servitors to help with the ether. Then came their Dark Ages. Left to make their own existence in the void of space. Houses fell and Kells died. New Houses were created with new systems of hierarchy. Like tithing in the Hive ether was given as means to fight and be pirates. Docking arms became a new punishment for dregs. Its quite sad. Then after years of surviving...they found their god. They weren't Eliksni though. They were Fallen. Warped and scarred from space. They saw their god and wanted it back. They think they earned it. They ravaged humanity. They destroyed cities. They thought it left because of weakness. So they were going to prove their strength. Millions dead. But so were there for them. They knew without Traveler like us theyd die. But they lost their honour. Parlay and diplomacy replaced by piracy and savagery. They need the Traveler but have forgotten that we need it too. Have we proven we need it though? Thousands dead at our feet from magic and guns. Fallen wish to prove their worth. By any means. Yes they are now what we call evil. But they wish to survive. Thousands of years lost to these Fallen. Maybe theyve forgotten how to show honour and compassion. House Devils are exactly that. Devils. They pillage and scavenge. But look at Winter. They dig for information not mass genocide anymore at least. Even the Fallen are breaking apart like the Guardians have. House Exile is like Sunbreakers or Osiris. We think Osiris is evil not just for his sick tournament he puts on. House Exile may think the others are evil for what theyre doing. And no House Exile did not massacre the Moon staff. Crota and his merry band of psychopaths did that. House Exile just took up residence away from Winter Kings Devils and Wolves among tge darkest of our foes they never expected us to go back to the moon. Now their home is being invaded by us so they defend it. We are always on the precipice of Light and Dark. Look at our weapons our abilities. Look at what weve done. No good guy can totally wipe out a species Gods without being seen as evil. No bad guy could help the people of earth build the last city. We choose what our guardians do. No just because of puppeteer controls but because we are forging our Destiny. Ten fold we need to wipe Devils off the map. And sorry but i side with House Wolves in trying to kill the Queen. Slavery never worked on earth why should it in space.

As far as I can tell, the Fallen and the Cabal are not minions of the Darkness. The Taken, Hive, and Vex are. The Taken are controlled by Oryx, the Hive serve Crota, and the Vex are controlled by the amorphous thing at the heart of the Black Garden. The Fallen are the smashed and nomadic remnants of a civilization, and the Cabal are part of an interstellar empire of some sort. We don't know if it's brutal but basically benevolent like Rome, or something more in line with 1930's Germany.

Yeah their story is actually quite tragic and kinda makes you feel sorry for them. They're basically mad at the Traveler for abandoning them to the darkness

Eliksni aren't evil. Fallen are.

By that logic then nothing is evil in this game since everything is trying to survive, the hive are trying to eliminate us as a threat to survive. Same for cabal and same for vex.
