Ah, most of my free time is thinking about killing people in different ways.
I would want to torture somebody.
Like, Just having them tied up. Ripping them apart pretty much. First, ripping there finger nails and toe nails out with pliers. Second ripping there hair out as fast and hard as possible. Then, start removing thing layers of there flesh, as much as possible. Try to break a lot of there bones too, stuff like legs, arms, fingers, ribs, ect. Then have something like a hallway, or a basement would work, have splinters, broken glass, tacs, rusty nails, ect. and drag them back and forth through that for a half hour or till you get tired. Then to finish them off, just let them rot away in a pile of feces.
That or beating someone to death with a hard object. Something like a baseball bat, sack full of door knobs, brick, crow bar, ect.
Carving someone up like a turkey would be pretty neat too, I guess.
