Even though he will never fully understand or feel the pain she's went through, he will now have to wait and suffer receiving the conaequences for his actions. Also, why is he wishing he never talked to her? You're only saying that because of the choices YOU decided to make. Like we've said we've wished we never done something before, but when it's in a anime/manga it just hits different. (I'm still mad at him for bring another woman to their wedding ball! Yeah Karloi I still remeber that!)
