Some textures suggestions may be good... He was a vile and mad, and here he looks like a kind uncle

.
Yes, he was "mad," though not completely vile. He hated the nobility, and most of his "madness" was aimed at them. To the peasantry, he was severe, but fair (hence the peasantry's name for him, Ivan the Severe). As a child, he was severely abused by the ruling regency, the Shuisky's. They kept him cooped up, half-starved, ill clad, taking him out only to state occasions where their fawning to impress foreigners must have been evilly ironic for the young child. They allowed him no nurse, no tutor or friend, though he managed to get hold of some history books, paying special attention to ones on caesars, hkans and other autocrats. When he was 13 he suddenly turned his chief tormentor, Andrei Shuisky, over for execution, and took charge of matters for himself. From his experience with the boyars and the Shuisky family, he decided that he must look to the people, not the aristocrats, for his throne's support. To this end, he appointed low-born men to important positions, like his Chosen Council, and later married to a woman from a relatively low house that were popular with the common folk, the Romanov's. When he was 17, Moscow burned to the ground and the boyars, claiming it was witchcraft, murdered his uncle Yuri. When they started to threaten him, he started a long series of executions that were to years. His wife, Anastasia, died young, and Ivan suspected poison. This early death of his wife embittered him, and he came to feared the boyars. As a result, he had them tortured in scores, and punished the residents of Novgorod for a "conspiracy" in 1570. As his paranoia and madness grew, he even struck down his favorite son, Ivan, in a fit of madness.
So you see, his circumstances were kind of understandable, and it should also be kept in mind many of the good things he did.
He allowed the common folk to petition the tsar and issued new rules for local justice, taxation and government. He saw to it that Adashev, one of the low-born nobility whom he had placed among Chosen Council, appointed many good judges. He sent for scholars and artisans from Western Europe to help bring his country out of a state of barbarism. He championed Ivan Federov to become Russia's first printer, who set about printing many books in Greek, Italian and German. He greatly expanded Russia's land eastward all the way to the Caspian Sea, and built St. Basil's Cathedral (the structure Firaxis mistakingly called The Kremlin in Civ4). The great acts of cruelty, like setting bears upon people for punishment, did not come until later in his life, when all the ghosts of his past likely finally crashed down on him.
