Well that's it, obviously not of sound mind to kill your kid like that, and try to top yourself too.
In a correct frame of mind this wouldn't happened.
Justice needs to be done, and he will be away for a good while, but he's suffered more than anyone can imagine already.
God knows ho you'd feel if a kid died, but to be the cause of their death, doesn't bear thinking about really.
Every waking minute would be his punishment I'm sure.
