McGonagal was very strict but fair. She would have been completely justified in "Chamber of Secrets" to have expelled Harry and Ron over the flying car incident but didn't.

Then after he used it, she gave Harry a hard time for using the Cruciatus curse on Carrow.

Yeah, she was a much better teacher than Dumbledore. What would she have said to him about manipulating students into taking on dangerous missions?

I always loved her dry sense of humor.
