As a former Social Science major I'm very intrigued by the moral arguments happening in this comment section. That being said this manhwa is problematic by definition and here's why.
Humans are actually incredibly bad at compartmentalizing, it's the science behind our empathetic capabilities which are what make us apex predators. Humanities evolution is entirely based on how we understand eachother and that ability extends even to the world of fiction. It's why you cry when your fav characters dies, ur head knows they aren't real but the feelings of grief are as real as real can be. It's why we must be extra conscious of fiction we consume as our brain very easily bleeds it into reality. It's why therapists are so against heavily using dark humor, the constant joking normalizes the idea in your head and the right trigger makes it not a joke anymore. The same applies here. Constant consumption of such fiction will eventually normalize the idea in your head and the chances of you noticing it are low due to how gradual this process is. You would have to be constantly and consciously reminding yourself not to do so which is 1. Something I don't think most readers are doing and 2. Difficult to do as humans aren't particularly designed to do so. The critique of entertainment media with such content shouldn't disappear, if anything we need it more now than ever with the increase of younger generations becoming netizens at younger ages than ever before. Careless handling and normalization of sensitive topics always has and always will be a bad thing. Wether consumers are commiting a moral failure is a case to case situation, and in this case that argument isn't the point of my comment.
I'm not here shame anyone other than those with fetishes (y'all need help, and I'm being 100% sincere saying this) but in an effort to make you think twice about the media you consume even 1% more often as yes it does matter. It's matters a lot more than you know
All my faves are being dropped
