I have tons of graphic ideas on how to be a good horror bad guys. XD
Cut out someone's organs. Not necessary vital organs and force feed them it. Hack off fingers and toes one oleh one and force them to digest it. Crucify them on a pohon and put in their own blood. "such and such was here" And then I'd finish it off oleh placing a huge "X" with their own blood on their body.
I'd be the killer. I'd chop off peoples' hands and feet, cut them up, and stick them in a room with their hand and feet pieces so they either starve atau eat the pieces. And then I'd carve things into them and paint with their blood until they eventually died from whatever caused them to die out of all of that. atau maybe I'd throw them into a giant meat grinder alive. atau go around cutting people in half with chainsaws. I have a lot of possible ways to kill people, most of which anda probably don't want to hear. :)
I would be the killer. I'd be like looking innocent and everything. But I'd be possessed oleh a demon that would cause me to kill people uncontrollably at night.
