I'll give it that much that Messiah is not an offensive name. But like CF thinks, and I concur, it is a crazy name for a kid that will impose a life sentence on them that they don't deserve. And so will Adolf Hitler Campbell.
I don't think there's anything to support this. The kid will likely be a fuck-up, but not because of his name -- because he has bad parents. In fact, I read a book that had a whole chapter talking about how your name is not related to your success in any way, except for correlation. If your name is Laquita Ray-Ray Jones or Shannon Michelle Jones, it will have statistically no effect on your quality of life, when controlled for other factors, like class.
It's just easier for the government not to get involved into what people name their kids, also.
