You've got a good approach to these updates, clearly, with how you prefer to tie concepts to gameplay directly. That's something I think you should make a rule, if anything, because a cohesive game is better than not cohesive. My two cents is to make the mechanics tied to these concepts reflect what kind of mindset you have to be in to perform them, and what that would really do to a person. Corruption of Champions does this well with their corruption meter, which makes you sluttier the higher it is, and is gained from doing slutty things, meanwhile keeping it low keeps your mind clear and focused.
