Pretty sure it's a cultural thing. I think slowly the perception is shifting, but it's still a big stigma in a lot of eastern countries.
I've never seen a manga or manhwa that didn't vilify an abortion, and I don't know that I've ever seen a character we're supposed to root for ever chose to have one, despite their initial reactions. They always change their mind if they're a "good" character.

I love kids but at this point I really need a story where abortion isn't demonized and shown as actual healthcare.
There are so many toxic omegaverse but not one omega got an abortion r u serious?
