Aria is 2nd rated villainess at best. Mielle is the true villainess in this story despite that she has like 2 IQ. This just shows that evil she was. Her whole existence is to harm people until the day she died.
While the so-called best villainess is busy developing and helping the industries. create job opportunity for mass, playing matchmaking for her best friend, rewards those who are working under her handsomely, and actually helping people in the dire situations even though she said the opposite, and she never used her authority and wealth to threaten those who disagreed with her. She is also very polite to everyone (including low tier maids) who is not Mielle and her evil friends.
Aria thinks she is a "fake saint" but in the eyes of those who knew her, it is literally a walking saint that descent from heaven to punish those stupid people.
