It is their nature.................

And it's not just the owners as many will claim. It's frequently the "sweetest dog I ever knew", a family pet that has been loved and well cared for since it was a pup. I've seen it myself with my Aunt's pit and another friend's pit. They are "great family dogs" until suddenly they are not. When my daughter was a child, there was no doubt in anyone presents mind that the sweet little pitbull would have killed her if allowed. There was no teasing or taunting. It was the first time the dog ever saw her and it was like a switch was flipped. The vast majority of dog bites are a warning to get back, leave my toy/food/puppies alone, leaving a couple puncture wounds. Pits are not warning when they bite, they are trying to kill.

What about pit lab mixes? A niece now has one and he is 60 # and a lap dog. Long nose half up ears and he points at rabbits. He worries me because he rarely barks.

A scorpion asks a frog to carry it across a river. The frog hesitates, afraid of being stung, but the scorpion argues that if it did so, they would both drown. Considering this, the frog agrees, but midway across the river the scorpion does indeed sting the frog, dooming them both. When the frog asks the scorpion why, the scorpion replies that it was in its nature to do so....... 😈

Here is a story that may interest you, it is another example of the behaviour you describe (written by a former vet tech, mounted police officer, and pit bull apologist) :
