In the case of 3 demons and 1 man
Why would any demon eat the human, because if it eats it will be the target. Notice that the demons are not sleeping. The demon who eats the man will sleep and will be a target now.
Although the demon(3rd) which eats the human becomes target, the others can'nt eat this daemon(3rd) because the daemon(2nd or 1st) which eats this daemon(3rd) will become the target for (1st Or 2nd) daemon. So none of the 1st or 2nd daemons will dare to eat the 3rd.
Infact according to me, either one demon will live or everbody including will live. Lets say 1st demon will eat the man thinking that if he eats the man than no demon will eat this demon, as the second demon will become the target. If all demons will think this way then no demon will stay will alive but one.
In other case lets assume that all demons think the other way round that if it eats and then sleeps, then it will get eaten, so no one will get eaten.
Problem says "Demons are very smart, and will always chose to stay alive than risking their life.".
So the most probable answer is that nothing will happen.
The question doesn't say anything about a demon sleeping after eating another demon. Hence any one of the demons will eat the sleeping man and all 65 demons remain.
1 demon 1 human

2 demon 1 human
nothing happens.
3 demon 1 human
one demon eat the human.
Explanation:
if there are odd number of eaters and one sleeping target, one of the eater(demon) will eat the target(sleeping demon/man).
if eaters are even(>=2) nothing will happen because if he eat the target he will become the target,Now eaters will be odd and according to first case target will be eaten, so nobody of demons want to become target so nobody eat.
So 65+1
one demon eats the sleeping man.
nothing happens after that.
