I think if any dog is human aggressive (true human aggression) regardless of breed it should be put to sleep.
Walking around with a human aggressive dog or keeping a human aggressive dog around is like having a loaded gun with the safety off. Its way too risky and no matter how hard you try to keep this dog from people at some point in the dogs life it will be around people and kids. And it could be disasterous, just like say that was a kid getting a hold of the gun with the safety off.

Not to compare dogs to guns but what I am saying is its the responsibility of the dog owner to keep their dog from being a public threat. And a human aggressive dog is an unstable dog and the results could be very very bad. So I believe the responsible thing to do after being evaluated for health issues and being evaluated by a professional dog behavior expert. If thy dog is human aggressive its better for everyone involved for the dog to be put down.
