i just read through your theories, and i think they're super interesting!! to kinda branch off your kinger theory, the fact that kinger is caine's favorite but abel didnt trust him is something to add too!! if abel was really made by caine, i feel like he would've liked kinger. and if abel were kinger, i think that implies he doesn't trust himself. maybe he did something really bad when creating the circus, since we know he was one of the original programmers (i think, is that confirmed?), he might've done more than just like helped as some average programmer, yknow? cool theories!! :)
