I used to have an american pit bull once (which he died cause of snake and stuff) and yes its true. they only behave bad if people treat them bad like my step father and elder brother did. and he was really big and 2 or 3 years old at the time? but anyway, he only treated one person nice and that's my grandmother. because she fed him every day. he knows that my grandmother is the nice one in the family so he treats her very nice by laying on top of her. I one time heard my step father yelling and beating him cause he pushed her idk I wasn't present at the time. but yea. pit bulls could be the nicest dogs in the planet if ppl could just learn to treat them nice and not train them to be soldiers.
