Jack, I think the problem is that it does not belong in a thread that is discussing Rousimar's persistence, or the good things his mother did for him. If this were a documentary on Brazilian society, I could understand. But there are a ton of reasons that could have happened. Maybe she had money before and something happened (unlikely in this situation, I agree), maybe she was raped, maybe she was taught a bunch of bad principles and ideas by her own parents. The point of this, though, was that after her decision to have those children - which I will agree she should not have done if avoidable - she took responsibility and sacrificed her own well being for their good. Many people follow up the poor decision to have even one child with a lifetime a shitty parenting, raising someone who will do the same a generation later. It sounds like this woman matured, took responsibility, and did her best to raise them as best she could.
Making your comment here would be like if you read in the news that a homeless man ran in front of a bus to save a child's life and died. Then the article was said how heroic the homeless guy was and how sad his death was, and you responded with "If he hadn't been homeless, he wouldn't have been there in the first place"
