The fact that there is so much focus on the player getting to have sole authority over what their PC feels, to me, seems to be a sign of the narrowness of the locus of agency in a lot of RPGing. That the only way the player gets to express their agency is via authoring the colour of what their PC feels.
(And I call it colour deliberately - because in a typical, conventionally-structured RPG it's not as if being able to author your PC's feelings has any effect on the actual outcomes of the actions you declare for your PC.)
