A line quoted by the main protagonist and our titular heroine in season 1. Marinette aka Ladybug
And yet when evil was unmasked she chose to turn a blind eye to his actions.
She chose to turn a blind eye and turn of all sense of logic and sense of reason.
She chose to ignore her own conscious and all the cruel and psychopathic manipulative actions PAST AND PRESENT.
And she gave evil exactly what he wanted. She gave Hawkmoth/Monarch aka Gabriel Agreste what he wanted!
Did she forget how he emotional and psychologically terrorized her, her family and her friends. How he manipulated all of them. Did those events get erased from history?
No. She found someone else to blame.
She couldn't allow her love one's father name to be sullied so why not scapegoat the girl no one likes as the bad guy?
Why? Because she had so many chances to change and everyone around her has "tried" to "help" her. (Lies always make hypocrites feel better about their double standard morality.) But as her once close friend said "You'll never change."
Evil doesn't triumph when good people do nothing. It triumphs when "good" people play favorites on who deserves redemption and who is beyond it.
Marinette you are not a hero in my book. You are selfish, entitled, manipulative young girl who thinks because she's nice and people like you she can get away with bias behavior and playing favorites. You did nothing to help Chloe when she was suffering and instead you pushed her into the arms of her abuser. You knew Chloe was falling behind in class and you did nothing.
"Evil triumphs when good people do nothing" Without good people to hold us accountable or help us become better we fall victim to the sway of vices that we know.
That is exactly what happened. Evil triumphed because their were no good people to stop them.
Just complicit and blind eyed fools.
