Both Pumpkin Night and Revenge Classroom are shown to have female antagonists that want to take revenge on their classmates. They're both also shown to have no bounds for gore.
Both mangas have a FL who is reading to kill people as revenge. I personally prefer Pumpkin Night in most, if not every, aspect, from gore to the mentality of the FL. Of course, both delve into similar themes and the premise is more or less the same so you will probably enjoy both.
Nothing interesting is happening in Makoto Ozaki’s first year of high school. His life is a series of quiet humiliations: low-grade bullies, unreliable friends, and the constant frustration of his adolescent lust. But one night, a pale, thin girl knocks him to the ground in an alley and offers him a choice. Now everything is different. Daylight is searingly bright. Food tastes awful. And worse than anything is the terrible, consuming thirst. The tiny shames of his old life have been replaced by two towering horrors: the truth of what will slake his awful craving and high school itself.

If you like Magical Girl Site, you'd like Revenge Classroom because both manna's are based upon bullying. They also have mental illnesses and tragedy in the respective plots. Both manga's are quite similar to the other.
