Back then, if he didn't decide to follow his mother's wishes...
But he couldn't hate his mother. Karolina was a good mother, at least to him. Karolina fights alone in the palace, fighting over the King's favour with dozens of concubines. Leonid really wouldn't have survived were it not for her cunning plans and schemes.
As soon as Karolina realized that her life would soon end, she became impatient. The King cherished Karolina, but she is not a Queen. Her background and upbringing are not as grand as the Queen, Cecilia's mother.
She should have been content with everything up to that point. The King dismissed the other concubines, crowned Leonid, her son as Crown Prince, and even made Karolina a Grand Consort. Despair because of her illness and her fear of Leonid's getting into trouble in the future, not to mention her greed for happiness. It all made Karolina decide to kill the Queen.
