Comments of chapter undefined of Dimensional Journey From To-Love-Ru

Little heavy subject so I'll line break it below. Click the arrow to reveal the rest of the comment if you want to see/answer the question. So earlier we found out MC plans to go after his daughters as well. This along with the MC being a pedophile made me wonder something. At what point is father-daughter ****** better socially than pedophilia? For example, lets say the man in question is 25 and his daughter is 18. At what age would a girl have to be where the ****** is more acceptable.
