Merida would be a better pick for wrath, because she let her wrath overwhelm her.

I could see sloth in Mulan; in the first part of the movie she is lazy.

She was super lazy at first, always looking for shortcuts and ways around actually having to do what she was supposed to.

This fits her closest. I could say pride, but not as sin. She has the right amount of pride

Almost definitely. i agree with everyone above.

At first she's kinda lazy and even she is cheating.
