I'll start with the first encounters of Destiny 1. We first fight them on Mars, thats their 'home' planet that they've taken over well enough for centuries, and humans of course knew this. With this fact, they are well established on Mars and it's kind of futile to try and take the whole planet back, so we let them be, besides, the only real value on Mars is Rasputin. The thing is, when we first go back, it's only to get access to the Black Garden, but the Cabal are just an obstacle in the way of finishing the fight against the Vex. So really, if the cabal are just an obstacle, we have no real purpose in fighting them, but just sort of do. Now because of this, if put yourself in the perspective of the Cabal, you can easily figure out its almost like you're being invaded again in your territory and need to fight off these Guardians. The Cabal were just minding their own business on Mars, not trying to invade or extend territory to other planets, until Oryx showed up. When Oryx showed up, we all know they made their own war with the Hive and crashed a ship into Oryx's and try to blow up the ships core, blah blah blah. They still never attacked humanity directly. If anything, the Cabal were helping humanity fight off Oryx and his army, but we decided to blast them anyways. On the attempt of them blowing up the ship, we had no real reason to intervene, like cool you guys are gonna blow up the ship, yayyyy for everybody. But we know as Cayde said, "They blow up the ship, the whole system goes with it." At that point, I'm looking on the perspective of the Cabal again, what the hell are these Guardians doing preventing us from finally ridding of Oryx, do you guys not want them gone???? Let's jump to Destiny 2 now, that's was all I remembered of them from D1. Now alrighty, the big old Red War, yes the Red Legion were the enemies in this. They directly attacked the traveler and us, blah blah blah, we all know. Are the Cabal the bad guys yet? Ehhhh. Its 'only' the Red Legion that attacked humanity and the system. I know I'm making a big stretch here not fully calling them an enemy because of all the other planets and systems they've destroyed, but I stand by it. Ghaul only invaded as a response to a Psion Flayers distress beacon, he was only fulfilling his allies request. Besides the Red Legion, the entirety of the Cabal still remain on their own, never assaulting humanity unless it was to defend themselves. On with Rasputin now. It was still only the Red Legion that attacked him, ding ding ding, no other army of the Cabal. So my same points go into this just like the Red War, only the Red Legion were the enemies that invaded, the Cabal as a whole still didn't. Onto Calus and his world-eater. They were never a threat, short and simple. He came over and invited the Guardians onto his Leviathan to see some action is all. That man and his army just chilled out up there, not invading anything or doing anything. My short final point is the insight terminus strike. What was our purpose in that operation? That was between the Vex and the Red Legion tapping into their stuff. We come in, blast everything, and don't even get well enough intel to do anything with. I see no point in this. Now I'm bad at concluding posts, so I'll just reiterate. I think humanity are the bad guys against the Cabal. All they did/do was mind their business and then some zombie comes blasting away at their stuff. How rude.
