As some canon proof to how jadedavekat shits all over karkats entire character: karkat literally has an in-comic argument with his future self about how stupid and selfish he is for wanting terezi in not one quadrants but in ALL of them and for wanting her “all to himself”. Its pretty obvious that he cant use the quadrant system, its just not how he functions, he would literally be unable to do it........ Which is how saying jadedavekat completely destroys his character (PLUS JADES TBH!)
youve given me an excuse to ramble about this yet again like the broken record labeled “shouty alien top 50 hits” i am so here you go
karkats entire character revolves around him being what is effectively, a closet human weeaboo. everything about his character should be informed by the fact that he does not fit into his society in absolutely any way and fits earths better, even if he tries EXTREMELY hard to overcompensate for it. his blood color, his lack of violent tendencies, his ability to empathize, his shit fighting abilities, and his romantic tendencies, his lack of wings as a godtier, hell even the nubby horns that are barely there. the other trolls are also like this to various degrees (vriska and terezis characters also tie into this) but karkat is essentially the poster child of this particular aspect of the comic imo. nothing about him fits whatsoever, to the point where vriska said that hed make a better human than troll, and hussie said in the book 3 commentary quote “…he exhibits qualities which are somehow more human than most other characters, which is ironic, because he is not a human.”
for him to get any sensible character development he has to move away from alternian values that are canonically toxic (remember that the literal villain of the story implemented them in order to exploit trolls) because this is at the core of the vast majority of his character faults. he judges himself by standards he shouldnt be judging himself by and is why he thinks hes utterly worthless, and is the reason behind his brash, negative behavior that comes from his mad scramble to overcompensate. he has to learn to accept himself through rejecting these values, or at least not viewing them as the end-all-be-all to start to get over this. (i dont think quadrants are necessarily bad, just like straightness in human society it just shouldnt be ENFORCED by pain of death) this doesnt just extend to him, but extends to the entire hybrid society he was put in charge of building…because how nonsensical is it for echidna to put some kid that parrots doc scratchs shit he was brainwashed into at the forefront of anything thats meant to be an escape from LE?
so the reason why i said i think putting karkat in any sort of poly relationship is character assassination is because it completely goes against his momentum here. him realizing he doesnt fit in romantically EITHER quadrant-wise or polyamorous-wise like we saw him edge towards on-screen and like his ancestor did was the first step in him coming to any sort of relevant understanding here along with him admitting that he isnt good at fighting. having him go back on the terezi development and compromise with an alternian-lite poly relationship is literally reverting character development and also implies weird shit like him not feeling about dave in the same way he did towards terezi or the signless did for the disciple, and is just plain ooc irt his insecurities.
this is why i also think people who say him getting over the jealousy is character development just dont get the whole troll context he comes from and dont see that he was doing that regardless of jealousy being punished by death in his society. also you can get over insecurities that result in massive amounts of jealousy while still being in a stable monogamous relationship, those things arent mutually exclusive…in fact im positive that just him KNOWING that hes entering an exclusive relationship and accepting it as a valid option to begin with that fits him the best and is actually something he wants is enough to quell his insecurities and calm him tf down a lot (versus unreliable vacillating quadrants and sharing partners) along with his general growth in maturity he already went through
