im not sure if it just goes back to the start of life or if you go into a different plane of existence. but theres no saying that this is the only level there maybe be another 500 levels of shit to go through before "the end". theres also no saying that you wont remember the previous ones when you go to the next one anyway. maybe just the corporal ones you cant remember but tbh i cant see there being a ton of corporal body levels.
i agree with you that any decision you make is known that you will make that decision. if you over think it and try to purposely choose something different then you normally would, that is determined that you would behave like that. there is no getting around it. no matter how much you try to think and plan and make moves and decisions, that was all preknown you would do all that, or lack of all that.
