Yes, I am happy about that! You'll find someone after Issei, so that isn't a problem. You've freed yourself of him, and you didn't even have to beat him into a pulp first, which is good!

And I think that's it. He helped set in motion the events of the SBURB we see on the community for both trolls and humans. And he claims he helped nudge events to cause them into play, which may even involve the individual harm of certain trolls on the community and definitely did involve preventing help from coming to others. And he's harmed you, which I believe counts as well.
