No harm intended
he is a human who thinks he is divine and makes others of his belief...believe that he is divine.

M*W: I don't think the pope believes he is divine nor do any of his followers. He's just a man in a high religious office. The pope's infallibility does not cover everything he says and does, the infallibility part of his job occurs when he 'speaks from the chair' or represents the RCC officially. However, before the pope 'speaks from the chair', his words are carefully constructed by the college of cardinals, so whatever the pope states in 'the chair' is representative of the whole RCC.
I am no way implying here that the pope is truly infallible. All that means is his being politically/religiously 'correct,' if that's even possible. The official word always comes from 'the chair.'
IS the Pope guaranteed to go to heaven?
You left off many other possibilities that are more descriptive, not the least of which is a deluded patriarch that is also an opportunist who, when presented with the head of state and cult status that he's attained, wields it as though he is a divine entity. His deception goes much further than "convenient liar" and into, perhaps, sociopathic delusion and opportunism.

M*W: No, but not because he's not sinless, but because there is no such place.
