I am having a hard time with this decision because I was young when I got my first APBT of my own. I am just afraid of the what ifs.
I think you answered your own question. In my opinion, when it comes to an animal, there should be no doubts. If you are having second thoughts, there must be a reason, even if you aren't sure what that reason is, it just don't feel right, then don't do it.
But that is just my opinion.
