How does one tell the Pyramid that one of their own was sent out to slaughter when he was given the Domain of Baton Rouge by the Prince of Naw'lens? Because clearly the Sabbat Pack is blameless here, they were just defending themselves.

Blameless Sabbat? That's an inherently contradictory phrase. Like "kind Ventrue" or "non scheming Setite" or "Wise Gangrel" (Beckett notwithstanding) But "blameless Sabbat"??? ....does not compute Abort, retry, fail?
