Even when Emperor Mieji, Hirohito's grandfather in 1867 granted a constitution to his subject that stipulated that the emperor was " sacred and inviolable" yet, surprisingly to many Hirohito did not believe in his own divinity and never see himself as a god. The people generally believed that he was a god who possessed miraculous power that is why the wars Japan fought in the 20th century were waged in the emperor's name. but he had limitations and even said most of the wars fought were against his will but has to consent to his ministers showing that even if he is the king he does not have absolute power.
all of this points to the fact that human divinity is almost impossible.
absolute divinity also contains in my oppinion the irrelavance of the time dimension since humans are no four dimensional beings, we can clearly say that humans are limited.
but some think that these limitations are natural and humans have to fight for survival.
