I think as a work of art it's 'overkill'. I also think the idea being presented is a bit trite. This kind of overt moralizing doesn't usually result in really great works of art. Art works better when the artist allows the viewer to fill in the idea in his own way, for himself, with whatever feels pertinent to him. The trick, though, is to present enough of the content, and in an interesting enough way, to invite the observer to want to do that. I feel like this artists didn't trust his observers to be smart enough to follow his moralizing on their own, so he stuffed the sculpture full of obvious 'clues' to make sure the observers wouldn't go off in their own direction.
Sadly, the mental meanderings his observers might have gone off in would probably have been more interesting than the moral 'one liner' the sculptor insisted everyone must observe.
