You don't think I still regret it, dad? I do. Every day I feel it and still have nightmares. If I hadn't been strong enough to force Baby out, I would have been solely responsible for earth's demise. And even if we had defeated Baby out of body, how could I bring myself to tell Goten I killed his father or Gohan that I killed his daughter? Those two considered me their good friend and I betrayed them by allowing a monster to overtake me. But even if I train and push myself, those feelings I have now won't go away.
