middlepath- “Whether or not we should halachicly mourn her death, it really doesn’t take away the fact that a Jewish person died at a young age, and I am saddened at her death. “
In other words, you don’t care what the halacha is, you’re going to feel how you want to feel. If you want to say that the s’a is not applicable here (she was a tinok shenishba or something similar) that’s one thing. But do you think it’s appropriate to just discard a halacha because you want to feel sad?
