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.
Darkness-Induced Audience Apathy: Our heroes are psychotic murderers who will never be punished, their clients are usually monsters who have no chance to be redeemed because they always die, and the rest of the planet is full of assholes. Why should we care about this series again?
Designated Hero: While we are supposed to root for these characters, Hunter is a psychopath who enjoys "assisting" the suicides of various people, whether they are willing to go through it or not, and Arcturus is too ineffectual to question their methods and just goes with them.
Nightmare Fuel: At least one of the deaths is so gory that Arc vomits (and Hunter gets hungry).
Autumn's death. She got her whole digestive tract torn out through her mouth.
A one-shot gag comic showed the results of a botched shotgun-in-the-mouth suicide that managed to be this and hilarious at the same time.
Strawman Has a Point: At one point, a pregnant sow decides to seek out Hunter and Arcturus because she can't afford an abortion. When they refuse to kill her on the grounds that she's pregnant, she calls it an example of "typical pro-life hypocrisy". Arcturus argues that they aren't murderers. However, no matter what you may feel about abortion, the sow is right about one thing: they are hypocrites and murderers, because their victims always back out at the last minute, only to get killed anyway.
