I really don't think that either you or I are in peril from any supernatural being, now or after death.
It seems you read my mind.
Otherwise, it would look as an engineer who built a robot, then he warns it that it will face real bad consequences if it doesn't follow its embedded instructions properly
In other words, a living thing which is given a sort of living flesh (as the human living one) only... will end up returning back to the state of void (the state before its birth/existence).
So whoever perceives in himself a living flesh only (so he sees himself being guided in life by its instincts only) is free to do anything he sees good for him. He will simply return back to the state of void when he lost his body for good. Almost all people on earth enjoy following their instincts only. Therefore, they are very important in serving the material world; by building and/or destroying (because by doing both the material world can run properly... but this is another big topic).
I have the impression there is no need to talk here about something that one may perceive other than his living body.
But if your beliefs bring you comfort and a sense of being in tune with your world, then I wish you well.
As I pointed earlier I can't accept an idea while being based on faith. The idea has to be useful to me and logical (based on the same logical process by which I accepted all precious ideas, scientific or else). So most of what I discovered about the real life is not supposed to be known by the common people in the world because revealing certain natural truths in public (via satellites for example) are considered taboo by their powerful rich classes (in any region on earth). So it was natural that Jesus was condemned to death just for revealing them in public.
Even in Science (I am an independent designer in electronic and programmer), I discovered, about 40 years ago, a novel solution in data communications (it was an MS thesis) that even IEEE denies the possibility of its existence (though I used it to scramble my private RF short-range voice transmissions in the 80's and for many years when I didn't have a phone line at home).
So I didn't need awaiting an idea to be approved by the world's Elite (religious, scientific or political) in order to accept it. It happens I am given a human brain as the one that those Elite have
