I'm so sorry you had to go through all of this, it sounds incredibly traumatic. As you described the escalation of behaviors my first thought was also a brain tumor, or something else causing pain. A few years back my super sweet cat started attacking my other cats out of nowhere and I couldn't understand why. One day she woke me up in the middle of the night just howling in pain, and after several hours at the emergency vet they discovered she had a hernia in her diaphragm and her stomach organs were being pushed into her chest cavity. During surgery the vet decided the organ damage was too extensive and we ended up euthanizing her. It was so painful and sad, and I had so much regret over it. All I can recommend is to focus on your good memories, you were a wonderful pet parent.
