For 2. She could have easily hid him with the Decocks for protection. But this would do nothing to help the state of the world since Karlsson resources are necessary. Doomed world means doomed Kane future. Not a good outcome for her.
As if it is anything better for k1 MC. There is already a ending planned where callista lives MC dies.
There are tons of outcomes MC would become regarding callista plan fails:
1) He may get killed as K1 (especially if the Olivia is evil.) Not because wantedly,, just because he is of torchur he faced in jail, could have made him phylogically weak because his mother never taught him how to survive even though she is so called genuis. She only teach him to love and enjoy the life and trust oilvia. But an olivia does not care about helping him, became a evil and want to kill him because he doesn't want to sleep with her or support her ideas. Now whose to blame? I can't blame MC because I seen in real life also, some people are weak and dumb. That doesn't mean have to die.
Yes it is the survival femdom world. But, mother should alteast warned him of those dangers. But she raised him as a feminine while she raised oilivia to fight and rule the world.
2) He may reject olivia to fail the gambit plan because he is in love with other lady like junko? Or he just don't want to sleep with olivia because it is weird. I would also not do that in real life if my sister turned out to be not my blood. She would be still my sister no matter what.
3) He may go for revolution as the dom guy.
