I'm an older brother as well, and I wouldn't do it either, even though I'd be extremely angry if I felt I was qualified. However, ever heard of Cain and Able? Read that chapter on Genisis in the bible. That, which is the first murder that we Christians think happened, was when and older brother was jealous of the praise given to his younger brother.
I have read that story (or at least I know the story).
Point taken.
