The main thing with Vicky's aura too is most of it stems from after Cherish showed up. Cherish can manipulate emotions to force people to feel what she wants them to feel. In her pov chapter she goes on about how despite her power not being capable of long term effects she can cause them through conditioning such as making people love her by making them feel love whenever they look at her for a while. Fans noticed this and linked it to Vicky especially with the timing of plot threads to do with Vicky and how close to this view it is to bring up the possibility of her aura being the same only for Wildbow to be very unhappy and declare its not the same at all.
I mean, I read Worm far after it was completed and probably read edited versions of it, but it always struck me as odd that Vicky was allowed to run around unsupervised with her aura that she clearly didn't have the self-discipline to control. And it is self-discipline, since it was implied every time she was called out on it, she was able to rein it in.
Yes, Cherish showing up and bringing up how constantly tweaking people's emotions unnaturally could cause long term effects, so readers seemed to have jumped on that, but it's also something that clearly makes sense. WB coming in later and saying, "No, that's not how it works" regarding Vicky's aura (or at least, completing dismissing the effects) shows a very poor understanding of human psychology/physiology.
Vicky's always been an odd character to me. And I firmly believe the Vicky prior to Leviathan and post Leviathan were basically different characters, because there are clear signs she has changed after all that trauma. I read a little of Ward, but ended up stopping simply because I didn't find her interesting as a protagonist.
I can't comment on the issues between the original version of Amy in Worm versus edited versions later on, but my impression that she was a teenager who got dealt a shit hand and didn't know how to deal, and eventually snapped like a yardstick over someone's knee. I never really cared for the woobie Amy that shows up in fanfiction, or at least not the versions of it I've read, but I also don't really think she's a monster or anything like that. (I've been told in Ward she kind of takes a swan dive off that cliff, but I didn't make it that far.)
Eidolon gets a' bit' of a bad rap when he genuinely seems to want to do good.
I mean, I don't outright blame Eidolon for the Endbringers - he had no idea he was doing it, and I'm not sure it was ever
really confirmed that he was the reason for them (maybe there's a WoG I missed somewhere). But given how Scion destroys him, and the EB's actions after, it makes sense.
I give him less credit because he was also party to a lot of Cauldron's shadier shit. My issues with him tend to be less on him, particularly, and more on him being a member of Cauldron and all
that entailed
. Especially since, unlike Legend, he wasn't kept in the dark of their really shitty things they were doing.
