Toby's Insanity (Insanity! AU)

Toby's Insanity describes an AU where Toby finds that his mate, Kiki, and his children, Rusty and Peachy, have been murdered, and he finally breaks, remembering everything that has happened in his life, breaking and murdering those who have harmed him in some way or another. (ily all this entire AU is probably a vent but whatever)
