完顏亮，依據《金史》的記載是一位弒君、弒母的「無道主」。而完顏亮會有「無道主」的惡名，除以金世宗為代表的金朝官員對完顏亮的史料進行揀擇與增刪外，有大部分是因其弒君與弒母。只是完顏亮真如金史所稱的「欲爲君則弒其君，欲伐國則弒其母」，則有再加探討的必要。
According to The History of Jin Dynasty, Wanyan Liang is considered as regicide and mother murderer who was called as ＂brutal king＂. The History of Jin Dynasty said ＂If Wanyan Liang wants to become the emperor, he would kill the older emperor; and if he wants to conquer other land, he would kill his mother who had the contradiction with him.＂ But his infamy mostly came from he slayed his emperor and his mother. Not only that, but the Jin Government had wiped out some materials and distorted history. So the author thinks this kind of opinion still have some room to discuss.
