I like to be a ghost or third person when reading fiction. It allows the reader to retain their own character, world view and morality.
I don't mind reading characters thoughts but I want to retain agency of myself, it allows me to decide when to empathise with whom and for reasons defined by me. I don't mind a narrator style guide.
When the story is written as the first person it forces me to inhabit a character, suddenly I have to understand the history and motivations of a person I do not know. I have to internalise their/his monologue and pretend to understand his feelings, fears and ambition in spite of the fact that I can barely relate to him seeing as I prefer to retain agency while studying characters and judging them.
A good book in this style has a narrators feel seeing as the older Jim Hawkins in Treasure Island is giving account of his life and adventures. This puts you in a position of being guided by a narrator to better understand the person but you are still given respect as a spectator of the tale.
If I am forced to be a character in the novel I have cognitive dissonance and I struggle to be immersed in the story. Is basically what I am trying to say.
