...cannot for one second understand how this woman could let her child go through the pain (and death) because of the lack of $80.
Nor can I, however, I don't know her or the facts of her life - I don't don't have enough information to judge her.
1. the child had pain
2. The parent knew.
3. The parent didn't seek help because of the cost.
If you need more facts than those, you must be disingenuous.
