40K is built upon irony and hypocracy, thats what makes it so good. And Primarchs, apart from the Emperor are the ultimate agents of order (or disorder) so therefore it would make sense for a Primarch to lead Chaos. For all Primarchs to stay loyal in a setting like 40k is just stupid and greatly reduces the character of the storyline. GREATER ORDER= GREATER DISORDER so if the majority of the Primarchs remain loyal, then one Primarch or an entity stronger then a primarch must lead Chaos. The only creatures stronger than Primarchs, besides the Emperor are greater daemons and they can't usually manifest in reality so therefore they can't be practical leaders for the Forces of Chaos. We NEED a Chaotic primarch.
