Cersei Milton's life, in the eyes of outsiders, was a perfectly flawless, radiant life.
The Third Princess, who from childhood had experienced assassination by her royal brother, collusion of political parties, and betrayal by a maid, did not feel disappointed by this flawed world, on the contrary, she reveled in joy because of it.
The more flawed the world, the more valuable it is to correct, and when she had slaughtered all the flaws to extinction, Cersei would genuinely feel happy for this kind of righteous killing and indulge in it. Since she was a child, Cersei realized that to achieve her ideals, she had to learn to conceal her true nature.
She had to learn, her never-ending, increasingly intense desire to kill ever since she was a child.
She could kill, but not in front of the public, she could massacre, but had to plant a rare plant afterward.
She had to learn patience, no matter how disgusting the mistakes of others were, she always had to be under the radiance.
