First I have to say, I've never had a truly aggressive, "I'm gonna bite a human" dog. I've had fear biters, but even he, was the type, "you put your hand over the fence, you remove it, I'm going to nip you on the way out" ..
He was managed 24/7, never truly trained out of him, it was genetics pure and simple,
However, if I ever had a dog that downright, went after a person or child for no reason and nailed them, ONCE if not serious, I would make sure it never happened again, Twice, the dog would be gone no matter who's failure it was, mine or the dogs.
I'd feel terrible, but I can not live with a dog with unpredicatable behavior like that
