“If you actually go on You Tube and look, there are a lot of cute videos of kittens and pits cavorting together to various cute musical backgrounds.”
There is no reason to not believe that this pit was a loving dog. These creatures just snap...when they do, they kill.
Again this is a risk with many dogs. But a German Shepherd, say, is less likely to be raised mean because of a clientele that wants the dog to be mean.
Let’s not go off half cocked here with bad science any more than we should go Chicken Little with climate change and bad science.
