I’d like to offer my opinion as former “edgy kid” and now currently parent.
Before I had kids, I found children just annoying.
I very much can understand the perspective of those who say “fuck Zombie kids, they want to hurt me so I kill them no prob”, they’re no different from objects that are bad and must be removed.
I did not see the other side of what children do, why they do and what their actual function is, and I didn’t care (and why should I have cared, got zero reason for it?).
Now as a parent - I try to be understandable for everyone - you put a fuckton of ressources into your kids. It might not be a “empathic” analogy, but imagine you poured months of your life, thousands of [insert your currency here] and enjoyment/love into something (a car? VR-Deck? Whatever it is that would get you high), that already begins to pay off in hours of fun and just feeling good.
Would you guard it? Of course you would.
Would you understand if other people be protective of it? Of course.
And thats just the “cold” ressource-centric side of it.
Now - I myself was quite unempathic in the past, I would not have understood how it would make me feel sad if my kid got sad. The view of people like me can be quite mechanistic at times, calls to “but think of the children!” or “how would you feel if…” would completely have bounced off.
So I can only tell the “younger-me-types”: Its a horrible feeling to think about the life of a child being taken for an normal empathic human.
Another input. Killing someone as a non-military or trained-anything-with-killing-person will normally traumatize you - yes, murderers usually traumatize themselfes with their crime.
Killing a Zombie that looks like a child, will do unrecoverable damage to a normal functioning human.
And devastate you as a former parent. Even seeing a child that “turned” will, in your quite moments, make you imagine how it happend and “lower your morale dramaticaly” speaking in in-game terms.
As a desensitized gamer / “troubled kid” / anti-social-cellar-dweller you might not feel the immediate shock as strong, but it will leave unextinguishable bad feelings that will crawl up on you in your moments of “weakness” or in your dreams.
So in essence, I think the debuff for killing child-Zeds is absolutely sensible.
In Addition basically what Mantar said - humans killing humans and being fine with it requires a serious mental illness (like psychopathy or psychosis).
And another comment to the “psychopath” - word.
”Psychopath” is not an official defined term in psychology - so basically everyone can say it is what he likes it to be. What people usually think of as a psychopath is someone with reduced empathy in addition to other neuro-divergent traits like sadistic tendencies and also things like machiavellism, narcissistic tendencies or other in the same category.
That being said. Its a pop-culture game about surviving the apocalypse and if it got too realistic, it would just suck.
If it would be realistic it would be called a simulation, not a game.
