Throwing A Wretch Into It

AITOOW thinks that Covenant House commercial may be a tad insulting? They use amazing grace. The part where it says "save a wretch like me". Are they calling all these kids wretches? I thought they were just victims. Wretch implies something more sinister. Not that some of these kids aren't on the streets because they have become the problem. Not because they have had problems thrust upon them.
