Why did the emperor kill the queen?

In the palace wall willow, the emperor didn't really kill the queen, just for the sake of imperial power, let others kill the queen's children without making a decision for her, and the queen died in grief and despair day after day.

The emperor was born in a cannibal harem, and his mother princess had no right to be spoiled and killed, so he longed for power more than anything else. After he ascended the throne, in order to consolidate his regime, he let others kill the queen's children without making decisions for her.

The queen died in grief and despair day after day, so she never forgave the emperor until her death.

It is difficult at home and abroad:

The emperor is not qualified to be a husband, because he failed to live up to the feelings of the harem women, and even used them as political chips and as a tool to stabilize the former dynasty.

But as an emperor, he is excellent. He punished corruption, attacked the city gates, resisted foreign enemies, quelled civil strife, created prosperity for the people all over the world, and exchanged the pain of his own generation for the happiness of future generations.
