Like Ned Flanders?:lol:
'You killed my child...okilly dokily, have a nice day!'
I thought Mundus' reaction was a bit odd. He looks away at the point Lilith is shot, more like he's disappointed, more than upset. He's angry, but he's not saying 'how dare you kill my child!', he's more concerned about his image, more like 'how dare you pull one over one me and make me look weak!'. I don't think he destroys the city out of grief, but more anger that the plan he thought was foolproof had just gone terribly wrong and resulted in him looking vulnerable as the child is an extension of him. If it can be killed, what if it gives others an idea to take out Mundus.
