It’s literally a terrier breed. It’s what they’re bred to do. They’re all varying degrees of cracked out regularly and people though breeding one jacked breed of them was a) a good idea and b) okay for your average dog owner.
Kengals, malinois, hell even gsds; so many other breeds are equally as lethal and do just as much damage but they’re harder to obtain for the most part. The issue is that bullies (or bully breeds) are easy to get and people are either ill equipped to deal with the breed or are ignorant/neglectful dog owners.
