The Hitch said:
After Morgoth's defeat, his lieutenant Sauron gradually rallied many of Morgoth's servants to his own cause, and during the Second Age established himself in the land of Mordor. Sauron lacked the raw power and malice of his master, but he was far more cunning, and seduced many to his allegiance with lies and false promises. In the Second Age, Sauron repeatedly used his fame among Men as Morgoth's erstwhile lieutenant to portray himself as Morgoth's representative and thus gain the allegiance of his former master's worshippers. Similarly, in Númenor following his capture, Sauron became very powerful by seducing Ar-Pharazôn to the worship of Melkor, establishing a Cult in which it was only natural that, as Melkor's foremost former disciple, he became high priest.[9] This cult exploited the Númenórean fear of death by claiming that human sacrifice to Melkor would grant the Men of Númenor immortality. In actuality by turning away from Eru and the Valar they only dwindled more rapidly. Sauron used this religion among his means of encouraging Ar-Pharazôn's invasion of Valinor, which resulted in the destruction of Númenor by Eru. By the Third Age Sauron came more often to propound himself, rather than Morgoth, as the object of worship for his servants and subjects, but in his pride also portrayed himself as Morgoth returned when it was more convenient for him to do so.
You are right, Vino is MORgoth, and NIbali is Sauron
