You're so right.
It seems that many people today have to find someone to blame for every single bad thing that happens when sometimes things are simply accidents, and sometimes tragic ones.
Heck, beyond the simple accident. What if it was a totally boneheaded screw up? It still happens. And in this case, the consequences are so brutally irrevocable, and so permanently damage the lives of the mom and dad who must live with it forever, that what else is there to say? It's as you say, I believe. They need love and consolation.
Anyway, I don't believe they were trying to murder the kid. They made a mistake. I remind myself of this sort of thing when I'm driving in my car, or doing anything where a wrong move or bad judgement could cost me. People forget that life has sharp pointy teeth, and sometimes shows no mercy. That's why they judge, I believe. It's a defense mechanism. They don't want to deal with the reality of just how harsh life can be, so they rationalize it by placing blame.
