I guess owners of pit bulls are more cruel than owners of other dogs. I am not being sarcastic. If the above premise is valid, it's the only conclusion one can come to in view of the number of pit bull attacks on humans and animals.
If you look at the people who are attracted to the pit bull breed you will see that they are at a higher risk of abuse. Most of these dogs aren’t being purchased by the well adjusted family. They are being bought by people who don’t even take care of their kids.
