Do you remember the way she treated Hagrid? She was so mean to people like Hagrid. She sent him away! Dolores basically hated him and wanted to get rid of him! That is so mean of her! I know you are all thinking about Hagrid, but do you remember the way she treated Trelawney? She also wanted to get rid of her! So mean! That is the fourth reason why Dolores is so horrible.
