Your honor my client was overstimulated. He’s a found object sculpture artist who doesn’t have access to the medications he needs to function at a socially acceptable and comfortable level. His effigies of grave robbed corpses were an elaborate, symbolic art piece meant to discuss the unimportance of background, class and identity showcasing that in the end, we are all flesh clinging to bone... it was all a social experiment. He never killed nobody.
Slasher villains using sharp weapons is a classic thing and a staple of the genre, usually with the subtext that it's creepier and scarier for someone to chase after and stab you as opposed to them just shooting you from wherever.
