yeap for Hirrud it is his mentality turning him into a weak femboy would be an appropriate punishment for him in addition to preventing him from continuing to assault and kidnap kitties.Damn dude... And here the authors just had the idea of turning him into a girl, since, as we know, being a girl is fate worse than death.
Although, I would personally just enslave him, TF him into a Femboy (ala Nikol)/pretty boy (ala Rooh)/keep him as he is and train him into a decent (enslaved) piece of well behaving beef.
Heh, if only someone would write it...
