This is in Goblet of Fire, when the kids go to meet Sirius in the cave, and he says that Mad-Eye received special dispensation from the ministry to perform the Unforgiveables. Then Sirius says "I'll say this much for him; he always brought them in alive, if possible". So Moody undoubtedly DID use the Killing Curse, but tried to avoid it if at all possible.Originally Posted by Gmariam
I'm not so sure the governmental repercussions would be that big; by that point, nearly everyone was in a state of constant terror. If James had killed, say, Rosier (James didn't, Moody did, but let's not worry about that for the moment) and James was able to demonstrate either that Rosier was Marked or was attacking James' family, he'd probably have gotten away with it.Originally Posted by Gmariam
But I absolutely agree that the rest of the Order would have taken their cue from Moody.
Except for Lupin and Black don't do anything to correct this assumption. And according to Jo [*], the Pensieve memories don't show a point of view, they show it from a dispassionate third-party perspective. Harry came to the conclusion that James was a prat all on his own.Originally Posted by The Black Sister
