Interesting.
However, considering the fact that we're amoral animals who create our own laws and morals, I will answer your question with a question:
"Which standard, law or set of morals do people use to denounce anything, including child rape?"
In other words----you don't have an answer or refuse to offer it.
I respect you, dillo, but I don't really agree with you philosophically. I think my question in response to your does suffice, because you ask me what law or set of morals I'm using to pronounce the downfall of man, when one has to wonder what those same things can be used for anything else.
My answer may not be the one you wished to hear, but it's an answer nonetheless. Any actons can be justified by cynically questioning the created laws and/or morals of those very same people.
