Well curing "monsterism" and "corruption" are different I doubt putting a helmet on claire would reverse her current state, wanting to go from superhuman to human could be "regressive" but just making sure peoples powers dont mutate in harmful ways (nyx/henri) should be something viewed as beneficial. We also know that becoming a monster/human causes biological changes but corruption is seemingly mental/mystical (nyx got mind raped by "ghosts" for a time/being able to "hear monster whispers at night") so "corruption" should be much harder to cure.Oh, I don't think they're the "good guys". But curing monsterism is a practical goal even if you're not very altruistic, like you said it would be a big help for anyone working with superhumans. Though oddly, Markus Alderman said that Xanthe considered the monsterism-curing group to have a "regressive philosophy", so maybe he doesn't agree. Maybe it's not that the best he can do is prevent corruption, but that he just doesn't want to do more for whatever reason.
And yeah, Ella might have first encountered the MC at the hospital. It's that or at the homeless camp he ran away to, but we have that photo of her in the hospital, so that seems more likely. Which raises some ominous possibilities. Stephen worked for the institute that treated Syla, and probably had at least some idea of what they did there. And Ella considers the MC to be the only other survivor of...something, though we don't know what. Did Stephen give his child over to Tanos to be experimented on?
As the person above me says since he recalls the guy who told him "your life aint that shit kid" he would have to remember Ella, the only way for her to know him without him knowing her is too meet before him mom died.
Well we "know" Stephen meets syla, stephen likes her tiddies, stephen too horny to care about her shapeshifting/clearly being mentally messed up, stephen marries her (all confirmed in dream?) from here right now my guess would be: stephen gets job while syla is being "treated", syla lies to him about the treatments, MC is born and probably does some monster stuff or whatever ended him at same place, stephen learns whats going on and does some blackmail stuff to get mc/syla out of there but syla dies in order for mc to live/the lab sends someone to kill her.
I dont think stephen would give MC willingly for experimentation, he sure as shit wouldnt willingly give up syla for it, and that goes double when you consider how "above and beyond" tanos would likely go (like he did with amber/liz)
Considering cole is "angry" but otherwise "sane/functioning" I dont think it was "just" tanos experiments that are the reason, I think the real reason has more to do with whatever "bad stuff syla took in over the years" that caused her a "true spawn" to no longer be consdiered "pure"......beyond that would be rampant speculation but my money is on a certain raven and their lordWhich, again, is pretty ominous. What happened during the time he spent with Ella that Syla didn't want him to remember? If Tanos did work at that clinic, odds are good that he would have seen the human-monster hybrid that is the MC and wanted to experiment on him. Syla said that the memories she blocked would be hard on the MC, and Tanos' experiments would be pretty hard on him.
