No offence :
It's not rocket science to get a good start in this game ... everybody can get a K6 start and the whole process is transparent and explained in the walkthrough.
Content on the dom path is MALEDOM content in a femdom environment with lots of sex with willing females for Kane.
If a player starts as K4 and then maybe even goes down to K1pro, then this is usually an EXPLICIT choice of the player to see this kind of (sometimes extreme) FEMDOM content. A lot of choices on the sub path are just there to provide a variety of different scenes to cover special kinks like humilation, trampling, face sitting, pissing, whipping, killing slaves, etc ... recently there is also often the option to simply skip to the next scene if the player doesn't like the offered kinks of the content.
I have the impression that players misunderstand the game and the characters. I see the game mostly as a service where patrons can see their visualized femdom kinks and on the sub path can roleplay as a powerless slave.
It's a bit like in a fetish brothel where adult customers can choose their kinks, eg to be humilated and maybe whipped. Should the mistress in this brothel intervene and stop the whipping because whipping is an evil kink and may hurt the customer?
Cole and Calista can't intervene and free sub Kane since that would literally destroy the sub path for which the patrons pay. After all this is still a femdom game developed by a femdom lover for femdom loving patrons ...
If you don't like femdom scenes where sub Kane gets humilated or maybe even get killed, maybe better just stay on the dom path (and avoid Alessandra's special Secret Sub path).
