The thing you said here is true because Issei suffered a mental trauma after Raynare killed him, and I can't blame him for being affected. I suggest you read Volume 14 because is possible for Irina to have a child with Issei without falling into a Fallen Angel status but it requires a Magic circle, and while in the act the girl must not let the thoughts of lust enter her mind while doing this, and Irina wants to try this very badly because she actually wants to have a normal relationship with Issei because if she has thoughts of love during this ritual then he can get impregnated by him. You do know that they are having even worse problems than the Underworld about their population because they have a low birth rate like them, and they have certain requirements for their mates.
