Bound

When I was born, I was bound to a bracelet. I call it The Insanity Bracelet, also The Soul Bracelet. It is only bound to me, any other's who wear it get killed, instantly. The bracelet has the 'other me' bound into it. When it overtakes me, I kill people. And I do it on my own, and I know I'm doing it. My parents took it off of me and let me keep it, but to never put it on again.
