The author probably puts them together even though he killed them. That's why I stopped abandoned empress(I think) because it's crazy to me that someone like that would be considered the lead and forgiven for such horrible things.
Apparently in Abandoned Empress, according to spoilers, he was given some kind of magic potion and that's why he did what he did. Someone else told me this. I hate reading spoilers so Idk if it's true.
