These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Krug, the leader of a group of murderous rapists. After he and his gang escape prison for their previous crimes, they kidnap, rape, torture, and kill two teenage girls. The parents of one of the girls find out when the criminals incidentally stop at their house, leading to a bloodbath between Krug's group and the parents. Aside from leading a group of horrible rapist scum, Krug also brainwashed his own son and kept him hooked on drugs as a kid as a means to control him. Near the end of the film, he convinces said son to kill himself. So yeah, you definitely root for the vengeful dad to take Krug down with the chainsaw.
