"He's violent, don't get near him..." said no serf-human of the Imperium ever, especially when the only alternative was an obvious slaaneshi cultist - which would you have, that, or Khaine (admittedly himself a servant of nurgle... I guess those aren't exactly very good options in the grimdark of 40k)? Hmm, yes, as I thought all along, this is a Chaos world with close economic ties with Comorragh. It must be kept as a virtual paradise planet as part of some traitor primarch's petty chaos imperium's exports. There was never any hope for these children.
