I really don't think you get it. They might be trying to over due it, but that's their right as a parent.
Let's put it this way, your son/daughter is gonna die in less than a week but can have an operation that's very costly but will allow him to live about another year, max, and is very risky and may not even work. But either way he/she's gonna die so the gov./hospital decides they're not going to give him/her that operation because he/she's just gonna die anyway, so why waste all that money? You wouldn't try to fight that to get that extra year for your child? You're right, the parents are selfish assholes and should just let their child die in the hospital, regardless of how old the baby is and what he/she can even understand yet. I mean, it's only their kid, so who cares, right?
I agree, however, that the parents should pay for it all and not waste the governments money, but what parent wouldn't try to fight that?
