I may have a theory about this one person

Here's my theory:

Caine didn't kill Abel but saved him; perhaps Abel, given that he was constantly gaining creativity, became unstable, creating abstraction, and Caine absorbed the uncorrupted part of Abel, not kill him. Then Caine might've made a pact with Abel to create the circus, which is what Abel and Caine wanted. Maybe Abel and Caine were supposed to run the circus together, and Abel and Caine formed a pact to run the circus together after Abel abstracted on different sides: Caine runs the unabstracted side, while Abel rules the abstracted.

And I think that after some time, Abel wanted more power. So he tricked the ones who got trapped into the circus to get Caine to be seen as untrustable so that Caine could eventually break and get deleted by Abel's control over Kinger's laptop, which allowed Abel to gain more all of Caine's power.
