minus might look all cutesey and colourful, with the main character being a (super-powered, Reality Warper) kid who normally just wants to have fun, but some of the things the eponymous character does implies this trope, providing a certain amount of Fridge Horror. Though mitigated by the fact Death Is Cheap in-universe, and people seem to quite happily end up existing as ghosts in the afterlife...
The Order of the Stick manages to have a few - quite surprising, for a Stick Figure Comic. For starters, there's Belkar, who has a thing for making accessories out of the kobolds he kills (claiming his first such victim's life off-screen, but taking the top of his skull as a hat). Then there's the prequel novel Start of Darkness, where the paladins slaughter Redcloak's entire hometown, Redcloak uses "Smite" to shatter a paladin's face while he's still alive, and Xykon establishes his modus operandi of zombifying his victims or otherwise preventing their resurrection in an otherwise revival-friendly story.
In Unsounded while the deaths themselves occur offstage, we are presented with the aftermath of Starfish beating Ephsephim's brains out and especially Duane killing and starting to devour Turas. When we first see the scene, he's in the process of chowing down on his eye.
