I don't know, I'm gonna have to disagree with the face that he ate the messenger. My guess is that he enjoys eating the flesh of monsters that he kills. Maybe I'm completely wrong. He certainly does seem to have a few screws loose, same with his sadistic children, but I still think monster meat.
Also, I love all the sick fucks in the comments debating about how he is going to deal with these fucked up nobles. He treated the princess quite well upon meeting her for the first time following his death, so I'm quite intrigued how he is going to treat this family of fucked nobles. it definitely wont be pretty, and those sadistic little shit kids definitely deserve the worst of it. Maybe he will even feed them to kobold they were attacking?
Thanks for the update, and I cant wait for the next chapter!
