So, like, you're wrong, but there's a lot of nuance here.

1. Pitbulls, if raised well, can be some of the sweetest and most sociable dogs around.
2. They're still bred for fighting and violence and no matter how friendly a pitbull is, the owners still need to be very careful around strangers, kids, and unfamiliar dogs.
3. In the end, humans made pitbulls, and I think that gives us a responsibility to both take care of the pitbulls that exist and also not breed any more. Like a lot of dog breeds, humans have bred them to be miserable or dangerous for petty, dumb and selfish purposes. Maybe the smartest and most compassionate thing to do is to let the breeds expire while making sure the living are as happy, healthy and safe as possible.
