Okay I really like this one. Sue Sylvester was one of my fave characters. She along with Santana were the most hilarious ones on the show. Her break downs and the music that came with them always made me laugh so much. She had killer burns, sick quotes. She came off as 100% evil and seemed like she had no heart. But that is not true as several times she showed us that there is good in her. I decided to go with one of the moments she does so. This moment is when in the S3 finale she says goodbye to Quinn. Here's the video, just watch:
I gotta give a shoutout to the moment she took the fall for Becky though.
