I mean, sometimes a good story about a parently bond with a kid can just be that, and it would be a nice and cute story on its own
We have to admit a few things, first, just because something is immoral doesn't mean it makes for a bad story or bad characters, neither doesn't mean you are to condone it if you like it.
Second, a good story CAN be ruin if it goes for a taboo or an immoral option destroying characters and everything that was developed in the story, for example Usagi Drop, if you don't know about that infamous example, look it up.

It depends on a person. Some might like it and some don’t. For those who like it, the taboo/immoral option isn’t destroying the story but adds spice and complications of the story. For those who don’t, then it’s a case of bad story for them.
Honestly, the art of a story is in the eye of the beholder.

The example I gave doesn't add any spiciness or add useful complication, it comes out of nowhere and destroys what was previously build, it objectively destroys the characters and story, and as that, there are many more.
You can like a garbage story or ending, but you have to admit it is garbage to begin with.
But as I said, just because something is immoral doesn't mean it makes for a bad story or bad characters, I am currently reading about a story of a high schooler who has a crush on an adult, and they have this strange relationship, the characters are good, and the story is intriguing. http://www.mangago.zone/read-manga/sayonara_kyouhansha/.
Yes, yes, the art beholder, bla bla, art can be objectively bad and bland, and the beholder can be a dumbass as well, pretentious art is killing art and only serves the purpose to wash dirty money.
I do like garbage shitty stories sometimes, dumb character, dumb plot, but hey, it's entertaining at least, so I keep reading, you won't see me defending it, I like critiquing the things I consume even if I like it.
Stop lecturing ppl or acting holier than thou about this story. Yall watching and reading murder stories, are y’all condoning murder act or calling those who read it murderer?? A story is a stroy at the end of the day.
Dont like dont read. Your opinions arent that worthy.
