Ehh...the duty to call the police instead of handling it yourself first is different from state to state. Stand Your Ground laws and Castle Doctrine states offer various protections to those defending their property, not just their lives.
Anyway:
A man tries to kill my daughter better pray to God for mercy. I won't have any. I'll just kill him. If he succeeded however, that's where torture comes in.
Maybe that's just me, but I doubt anyone would do any less if their children were threatened, and they had the ability to do something about it.
They'd see the path of destruction between me and them from space.
At the end of Skin Game, Michael didn't use Uriel's Grace even though he knew that Nic and company were going after his family. I guess one could argue that since he suddenly had trouble walking that the Grace had gone back to Uriel, but he fought like a mortal, so I doubt that it had.
No, I'm pretty certain Uriel was still mortal; didn't he get a nosebleed or something during the Carpenter House fight? Regardless, Michael had the opportunity and motive to abuse Uriel's Grace, but didn't. Though, at that point, I think he was putting his faith in Harry, too, not just TWG.
