So by your logic and reasoning this poor woman apparently committed suicide(?)!
Lol, what?
Negligence is not Suicide. Suicide is intentional. If she put the gun in the childs hand and forced him to shoot her with her own hands, that would be suicide.
But negligence is what its name implies… Neglect.
If you are an idiot and accidently kill yourself, do you think that is suicide? Obviously not, right? You are of course still responsible for having done it, but an accident != suicide.
