"Do you have any idea how terrible the things you did really mean? Do you understand what it means to destroy a human being's sense of good and evil? Can you even begin to comprehend what happens when you awaken the monster inside each us? People should know in their hearts that food tastes good. They should always look forward to having picnics and wonderful places on their weekends. They should think that beer tastes good after a hard day's work. People should know how they should feel, that they're suppose to grieve, from the bottom of their hearts when they have to bury their own child."

— Wolfgang Grimmer · Monster

"There's nothing special about being born. Not a thing. Most of the universe is just death, nothing more. In this universe of ours, the birth of a new life on some corner of our planet is nothing but a tiny, insignificant flash. Death is a normal thing. So why live?"

— Johann Liebert · Monster
