Imo Immaru's whole "you're a mindless murderer, they're just lumps of meat to you" spiel falls completely flat for two reasons: -the player character has nearly no agency in a meta sense, a character questioning our decisions has no impact because we don't get to make many real decisions as far as the actual story. This sort of criticism should've been towards a character like Saint (if he hadn't already gone through that arc seasons ago) or towards the Vanguard as an organization, it means nothing to have an npc criticize our choices when we aren't the ones making them. -the guardian/vanguard, historically, tends to be extremely merciful when possible. At the start of this season's seasonal quest, we tell Immaru to call off his Hive that are defending Savathun's spire , and he's like "lol nah." My dude, we're basically gods, we weren't asking because we can't deal with them, we were trying to spare a few lives of our new ally's faction. We've done this before too. A lot of people might not know this (since Bungie removed it from the game), but Mithrax was first encountered as a normal Fallen captain, and we worked together with him and at the end of the mission chose to spare him. And again, when we fought Caiatl's champion, Ignovun, Zavala told Caiatl to call off her Cabal so we didn't have to kill several hundred of them needlessly, but of course she was all "tHeY fIgHt FoR tHe GlOrY oF tHe CaBaL, i WiLl NoT dEnY tHeM tHaT hOnOr" which kind of subverted the whole premise of single combat but we at least tried. The only time I can think of that we (maybe) killed someone who wasn't an active combatant was Uldren, and he was far from "just a lump of meat," that was both a highly personal revenge kill and somewhat justified as he was a serious threat. In fact, in a meta sense as well as being confirmed as canon in D.F.A.'s lore tab, it is extremely common practice for many players to simply run past enemies and not kill them whenever the game's mechanics don't literally force us to kill them to progress the mission. Despite being basically a sentient weapon of mass destruction, the guardian actually quite commonly tries to avoid violence when possible simply to avoid needless killing. Oh also he's annoying and cringe.
