Prick
Leonel didn't know how much it was the Vital Star Force affecting him, but he felt that he would have reacted much the same way. He had never lost his empathy, at least not toward the people he actually had connections to.
His father's death hit him like a truck. Aina's death felt like the same truck had backed up and dumped its load on him. He could still remember the rage he had felt when he had seen his brothers trapped in the bodies of beasts, and knowing at the same time that the Morales family was likely finished as a result of what he was seeing.
He had felt all of those things then, and he felt them just as strongly now after stepping into the Impetus State.
This made him feel better. In fact, it made him feel better than he thought it would make him feel. It was as though there was still a kernel of what was really him in there, a piece that wasn't entirely dictated by the Forces he chose to comprehend.
