A perfect summary of these 3 characters mah dude.
Since you mentioned morallity.
I generally avoid doing it cause of some traumatic experiences arguing in a Dungeons & Dragons forum (WHAT? Your character thought about killing? You are an evil piece of shit murderhobo! Good people don't think about killing! Trust me I'm a lawyer!), but I hope here it will go smoother.
One of the first things that anyone can observe when playing this game is that every named character is some kind of sociopath. And it's not like the rest are better. I always get vibes of the cyberpunk styled cynicism in the writing, although the game doesn't feel like the usual "retropunk" styles, for the lack of a better word.
Unhinged media pushing narratives, people caring more about sensationalism and acting silly in the face of lethal danger just to get a selfie with the hero, everyone seems to be fairly easy going with death. Those times where people act lucid and human, like for example during Supreme Minister's press conference where HERO is introduced, always cause me some sense of surprise. But at the next few minutes this turns on it's head, with some radio caster claiming that humans should put superhumans under the military or something, even after witnessing the death, destruction and the scope of the threat.
I get a lot of "The Boys" vibes, where some company creates superhumans and the management thinks that they can be controlled and used for commercials and marketing.
So the alignment is a bit skewed towards the "chaotic" and "evil" axis, to use DnD terms. People like Jake would be considered decidedly criminal in our world, but in the Superhuman world? I would agree that he would lean towards the "good" just for the mere fact that he isn't unhinged and is willing to think before he acts, without really having to recount his transgressions. Of course in the end, he masterfully demonstrated the concept of "slippery slope". One thing puts you in the path, second thing gives you familiarity, third and thereafter makes you a full blown criminal. So the question we, as observers, have to answer, is if Jake is redeemable or he should be punished by either death or imprisonment. I think WW found a good medium to punish the guy.
I agree with you that Alice and Michael are great friends but evil little bastards. I could characterize Michael as leaning towards neutral, because I can conceptualize him as a weapon to be used by others (which by the way make him more dangerous). For Alice, I'd say part of her allure is that she is very.. human. She is like the evil Amber. She cares, she worries, she can be very emotional, but she also has these same feelings when she wants to destroy her enemies, and as long as she limits it to mafia wars, it's mostly fine, but it can never be limited to just that, can it?
WW has created a great contrast with Alice and Tiffany. One is evil but emotional, the other is evil but cold. As far as fetishes go, that's fucking great! But I think it also shows how while people can find cynicism cool, they tend to "fall in love" with the more hot human emotions. Alice can be the sweetheart to those that like her, but Tiffany will always be the cold bitch, like her or not.
I find characterization and the effects that characters have on the reader fascinating. I could talk about it all day.
