"I regret it. I regret the murder. Let's just make that clear. I do have remorse for it, I am absolutely contrite. No one else can be more contrite than I. It's because no one else was more responsible but I can't change it. What do they want me to do? I can't turn back time and I'm not going to offer anyone romanticism by saying oh I wish I could change my places with the victim. It's romanticism. It's not gonna happen," Saito said.
