If someone is as mentally ill as to hear voices in their head, and goes as far as to kill their children [or anyone at that matter], then they should serve life in a mental institution, or prison. Personally, I think that murder should be met with the death sentence.

But I think that lots of people claim that they have a mental illness and were hearing voices just so that they will get off easier. If it is proven that they are mentally ill, then I think that they should spend lots of time in a mental institution and get help.
