Hammer of Olympia did him bad. Authors really wish to sell the idea of Perturabo being a manchild who throws tantrums and the like. From day one, decimation was a stupid thing to do, and throwing people at walls is retarded.
They never highlight the IW is the one routinarily tasked to do what others fail to do and their wars are not of conquest but of extermination...but that wouldn't be retarded, and the authors need the IW to be retarded.
