I take it that you mean a voice in my head telling me to kill them? No, I would know that voice in my head is just my mental illness.

Like the guy on the bus a few years back who decapitated someone. Apparently god told him that he has to kill this person immediately or he himself would be killed.. lol.. Like if I heard that I would act on it. 

If god appeared to me in my presence and told me to do it I would just assume that its a hologram or I'm loosing it. I certainly wouldn't kill my kids or anyone else for that matter.
