A proposal about Belarus from Hetalia: Axis Powers.
What's the Work?
Hetalia is an anime and manga by Hidekaz Himaruya. It is about countries and territories around the world reimagined as people. It initially started as more about history, but has become more of a "slice of life" kind of series, putting the countries in everyday situations. Belarus is arguably the main antagonist (as Romano is just mean to Germany, and Germany, Italy, and Japan simply reformed while Russia is not completely bad).
Who is she? What has she done?
Belarus (real name Natalya Arlovskaya) is Russia's sister who lusts after him. She stalks him, threatens people, bullies people and has zero respect for anyone but herself.
Freudian Excuse/Mitigating Factors
I'd say pretty high. She is an obsessive, selfish and lecherous woman who wants to be in a relationship with HER BROTHER. That's absolutely disgusting. She is mean to Lithuania, smashing his fingers, isn't very nice to her own sister Ukraine, I think she threatened Finland once. She always finds Russia and tries to CLAW AT THE DOOR, telling him to open up. It's clear she is mad.
Oh, hell yes.
