As far as I'm concerned anyone who kills someone for any reason and attributes responsibility for that act to a mythical being by stating my hand was guided by god is clinically delusional.

People who hear voices from or are directed by an imaginary man in the sky and don't respond to psychiatric treatment are commonly diagnosed as being permanently removed from reality and belong in asylums. If she had stated her hand was guided by koko the monkey god to kill someone she'd already be locked away.
