Neutered dogs

I had this pit I got as a puppy who hated every dog he met. Was about 5 months old when I brought him home and rt off the bat wanted to fight my cat gyp. I broke him off wanting to fight with her for the rest of his life that first day. Still hated other dogs and we eventually git him clipped at around a year. It didn't slow him down one bit, if he was given one inch he would get busy on another dog. I had him put down because of his dog aggression. He was great with kids and people and smart as hell but damn loved to fight. I really don't believe getting a male fixed will change him other than wanting to breed a bitch in heat.
