You cannot take a pitbull and treat it like a labrador or a golden retriever. You need to be very skilled in training dogs to take on a pitbull or a dogo or whatever. Yet too many novices and neglectful owners pick one up and don't take the time to train it properly.
You can’t train that killer instinct out. I don’t care how good a trainer you are.
The problem is, pitbulls have a certain aura that causes a lot of unqualified to want to own one.

They aren’t suitable pets. They have the unpredictable behavior and strength commonly associated with wild animals. The aura you speak of is actually their reputation for killing and not giving up once an attack begins - that is why some people simply have to own a pit bull. Some people also need to be photographed petting wild bears etc. - it makes them feel special when others retreat in caution. It makes some people feel ‘more qualified’ or special to own a pit. Those people just hate articles about pits killing adults, children, pets, horses etc.
