I mean I feel like there are other monsters that care for their spawns, regardless if it SEEMS friendly or not, we don't actually know their real true purpose. For all we know they seem to "care" so that they can mold them into whatever tool they want.
I thought this about the 3rd and the 4th, as they seem to always show some semblance of care even when infecting you they timidly approach you, with one even sucking you off and THEN infecting you. This applies to Demi's monster saving her from being strug up as well. But then there are other monsters like Michael's which practically almost eviscerated him just trying to give him his powers, in an almost mindless goal oriented manner.
Back to my point; the 3rd and 4th may seem "harmless" towards us even in Dead Ends (despite their overwhelming presence), or saving you from the 1st, but what if they're just trying to keep you unharmed so that you are a suitable vessel for their Arbiter/Origin to possess? There's a high chance that their nurturing presence is there to influence you in a corruptive, manipulative manner to fit their goal down the line, whatever that may be. Their loyalty has never seemed to be for you, but for either themselves or others of their kind higher up in the hierarchy.
-Angelina's monster wanted her milk and disposed of her when she wasn't needed anymore.
-Oscar's wanted to slaughter him and his family.
-Aglaecwif wanted you to give her a child.
-Kenny's Monster used him to get a stronger spawn for breeding.
etc. etc.
I'm not particularly prone to just believe they have our best intentions at heart just because they are hyper intelligent and SEEM good at face value. I mean shit, the Fairy almost killed everyone if Klaus didn't flee fast enough it probably would've, Alice included. But that's just my take though, Corruption seems to be related to monsters and their influence over your nature and sometimes actions be it through power (Jake's thoughts coming out of you) or the way you carry yourself (lack of morals, communicating with monsters, praising God, etc.). It's definitely not a POSITIVE thing for yourself in the longrun imo, unless your goals aligned of course.
Despite me loving the sleep around corrupt kill anyone who gets in my way route, if the 3rd or Mommy 4th want me to just give up my body so stupid ass Origin can get itself killed by Deus again or so Ella can have her way with me in her plans; I say FUCK that. As much as I love Ella, I plan on forcing some answers out of her and THEN deciding whether or not I want to help, in the meantime we can play cat and mouse if she fucks me on the side with her friends and keeps the game entertaining. If the 4th thinks a blowjob is worth selling my soul to some giant fuckin Eye for whatever monster politics they got cooking, I'm sorry to say but I'm not THAT religious, they'll have to revive their God another goddamn way, "caring" for me be damned.
Deryl's circumstances showed us a possibility that makes the monster motives very complicated, even if the resolution could be fairly simple. Let me explain:
The facts:
1) Deryl turns into monster.
2) By instinct he empowers his clone with his humanity.
3) MC beats monster Deryl badly, depleting almost all of his power.
4) The empowered clone returns to the whole and manages to reshape Deryl into a human.
5) Deryl thanks the MC for the beating, claiming that it was catalytic to that outcome.
If my point isn't yet clear, it seems that the power differential can allow the human side to win over the monster side. We had that indication since power protects the superhuman from monsterification during evolutions, but Deryl is proof that the interaction is more complicated than that.
A level 2 MC is for all intents and purposes, a weakling. So if he allows the Eye to be reborn, he gets dominated and absorbed by it.
What would happen if a naturally evolved level 5 with huge reserves of power allowed the Eye to be reborn? Would the same scenario repeat or it would be the opposite, MC dominating and absorbing the Eye?
Ella seems very insistent on MC becoming strong. She has high hopes that MC, who had his powers for a few months, will end up surpassing her in power which is odd to say the least. But even if it's possible, what's the damn purpose? We know that she doesn't just want the Arbiter to take over MC thanks to the Deadend. She wants MC to fight and choose his own fate. She says so during training 33.
This is all speculation but one of my theories is that Ella wants to create a god with a human-first agenda. We can't know the why. Perhaps the monsters are meant to win if things don't change, or perhaps there is some other apocalyptic event on the horizon and humanity will need the extra power to survive. Perhaps it's something more complex and more "neutral". But whatever the reason, for the superhuman to become god, they would need to inherit the power of an arbiter and a connection to the "higher plane".
The reason why I said that monster motives can be complicated, is because if that's the case, then why would they wait for the superhuman to reach level 5 and be able to resist them or even absorb/consume them? Perhaps monsters don't have the sense of self that humans have. Perhaps they don't care if they retain their agency or if they just live on in the superhuman's genes.
