The zombie kids I’m okay with, the description isn’t anything like with you listed, that fits more with some of the others that do not give guilt.
Now the kinderlings, if that thing can live through a burning building falling on it’s head it definitely isn’t a human child anymore, walking around with no face and all, and since some of the children zombies who do not give guilt turn into kinderlings, that then give guilt doesn’t make sense.
Also the waifs, fungal, and snot gobblers, from their description don’t make sense to give guilt.
All of that is easily fixed with a mod though, thanks for reminding me about them, going to make and add to my game before I play next.
