Remember that the goal in NTR is to fuck the girl and then take her away and then fuck her again until her brain becomes guacamole.
NTR doesn't mean ruining the protagonist's life, also because have you ever seen Inoda threaten Kirito? I don't think so, his priority is to fuck, because he's a pig. The only person who will be ruined is Asuna, you think she will have a happy life with Inoda?, I don't think so, if Inoda is nice to her it's only for one reason and once he has her all to himself, he can treat her like a worthless slut, I mean, nice shitty life xD
