Who is she?
She is the main character in the children's animated film, Mulan, by Walt Disney Animation Studios and is a princess that pretends to be a soldier.
Why I feel she does not qualify as purely good
She throws a shoe at Shan Yu.
And.
I know Shan Yu is considered one of Disney's worst and most wicked/immoral villains but you should be kind to other people, even people that are complete monsters, unless you need to be unkind and should be unkind with remorse.
