Antisocial personality disorder Joffrey is handsome and noble. He inherited Robert's iron throne, Bella Theon II's royal lineage from an early age, and was supported by the Lannister family. In fact, he is the son of Cersei and Zhan Mu of the Lannister family. Anti-social personality disorder, bloodthirsty, unsympathetic and honest, run amok, kill civilians indiscriminately and create riots in King's Landing. Go back on our word, behead Ned Stark in public, and trigger a rebellion in the north. He's playing with all the great rivers and mountains. It's a complete rip-off. Finally, he was poisoned under the witness of ministers, and there was no good end.
Joffrey's cruel image corresponds to the contrast image of his parents: a father who is indifferent to him, a mother who loves children but is selfish to the bone, a big uncle who plays around like a walking corpse, a little uncle who is too smart for anyone to look up, and an unparalleled prince position. What kind of children can he raise? But more complicated is human nature. Even so, Robert will still pray for Ned to protect his children after his death. Cersei will also collapse because of Joffrey's death. This kind of maternal love and fatherly love is in great contrast with the abnormal family model before. This is what fire and ice want to express, the complexity and unpredictability of human nature. But it's beautiful and great.
Joe has always shown his spoiled willfulness, thinking that after he ascended the throne, the whole world will follow his ideas and show his authority with all kinds of tyrannical and stupid behaviors. If anyone annoys him a little, he will try his best to get back at him, just like an innocent child slapping the ground angrily after a fall. He despised the dwarf uncle and the little devil, but was educated by the little devil for many times, so he tried to humiliate the little devil, because the rebellion of the Wolf clan abused Shisan for fun, because the unpleasant clamour in Winterfell imposed double taxation on the northern territory and suppressed the resistance by force, ran wild at the headquarters meeting, stimulated Wen Tai with old stories, and even glared at him. After that, he ignored the persuasion, violated his promise to Shisan in court and executed eddard stark who had confessed. All this is just a wayward child struggling as a helpless chess piece in the game of power.
