I think thousands of years make a huge difference, don't you? I can't claim to know what it's like to be a servant of God during Abraham's time, but ritual killings certainly weren't unheard of throughout mankind. God didn't really want Abraham to sacrifice Isaac; the point of the story was the willingness to sacrifice, not that he actually went through with killing his son. I'm afraid I'm not very eloquent or able to explain this subject well, though.
I think Abraham is quite different than the people in the article, because those parents have to ignore so much that has come to us since Abraham's time.
