So I wonder why it is, in your opinion, that dog breeders who have spent the same amount of effort to create breeds to be innately aggressive killers have failed.

The failure is not in your logic but in your premise. A fighting dog that exhibits human aggression is useless and will be quickly destroyed. Fighting dogs have to be handled by strangers during fights and often have to be handled while seriously injured. Docility towards humans is a must and is just as important as fighting spirit towards other dogs.

My premise isn't on trained utility but on natural traits. A retriever that won't wait is also worthless, however that doesn't mean that a good retriever doesn't have to restrain its urges.
