I hope that the jury, if they choose LWP for the murderer, that they can explain that they're doing it solely for the sake of the children and NOT because of anything presented by his family. Nothing his family has said means anything toward his character. He showed his true character when he murdered his wife. Who gives a rat's a about anything he did before that - I don't.
I have no problem with him getting the DP, but I also have no problem with him suffering and rotting in prison for the rest of his life.
