Birth is a Capital Crime

 All life is not valuable. Life is defection and treachery. The default response to giving birth should be to guillotine the baby. 

 Under normal circumstances, the marginal baby is going to starve to death anyway. At best, they will breed, and all the grandchildren will starve to death. In the meantime they consume wealth that could serve a bloodline which is not doomed. Skip the middle part, free up the wealth. Executing the doomed newborn is a mercy, killing them quickly and rarely instead of slowly and numerously.

 If the would-be parents don't like that idea, they can seek innovation in contraceptives or abortifacients.

 A live birth should require an intentional pardon from the local lord. Confirm it in person, provided that doesn't cause excessive anxiety.

 Being too soft to execute newborns is also a capital crime. If you don't like the idea, you're welcome to go from this mortal coil and stay go. Mortals have cows and pigs, there's no need to retain herds of softling livestock that walks about on two feet and shouldn't be eaten for health reasons. The argument is an obvious lie: "I don't like executing newborns because I'm an obvious waste of air and would have been executed as a newborn." It's an argument for [better late than never], rather than an argument against executing unpardoned newborns. Honestly it's cruel to force those who would argue against executing newborns to continue living, Forgive them for being born, and allow them to repent.

 The death gate cycle has an archetypal and evocative line: "For every life resurrected, another dies untimely." This is real, except IRL the line goes, "For every starving orphan fed, another dies untimely." For every diabetic or pediatric cancer patient saved, several others die untimely. Most medical interventions should be considered the equivalent of mass murder. (Doctors already know this, which is they they push so hard to administer them.) 

 In the death gate cycle, the untimely deaths are quick, usually freak accidents. IRL, instead of vaccines, kill everyone pointlessly bidding up the price of food, to avoid bubonic plague et al. 

 Immigration, of course, is likewise equivalent to mass murder. The city of rome filled itself with brown slaves. Over 90% of them died when rome fell, returning the peninsula to, lol, mainly the greeks. When you import an inferior, you're saying you want to slaughter their grandchildren or great-grandchildren in job lots. As should be expected of anything as catastrophically irresponsible as civilian migration. 

 I haven't exhaustively checked yet, but slavery is also a capital crime - for the slave. If you find a slave your country, euthenize them. If the slave traders don't like that, they can not traffick slaves. Ideally they attack the guards, giving you an excuse to summarily execute them as well. Better late than never. The crime of being alive has no statue of limitations.

 Conveniently this may be the one form of eugenics that isn't inherently corrupt. Imagine parents who can't secure a pardon, but deserve to. As you're not killing the parents, they have a continuous chance to prove themselves. Likewise, the behaviour of the post-hoc sterilized parents can be used for future reference, fine-tuning others who will not be permitted to breed, or correlating adult dysfunction with indicators found in newborns. Superior in every way to post-hoc revoking the permission to breathe.

 It should go without saying, but those whose newborns are pardoned are those who paid back the debt incurred by being born and continuing to draw breath. Perhaps commute the sentence to a fine. Make the debt formal, give it a number.
