Here comes the theoretical questions.

Why does Kaigaku become a demon slayer? Is it because he wanted to become 'special'? Why would he go back to exactly what almost cost his life.

Another thing is, in my opinion, Kaigaku is the most humanly out of the demons. I don't see him necessarily weak. You can see in the manga that he uses techniques after techniques, with no breaks between. This shows that he is a decent or great breath user. Kaigaku only became a demon for about 1 week to 1 month. He definitely won't know how to use the blood demon technique. What made him weak was his strong jealousy for others. To the point that he was angry through the whole fighting between Zenitsu. Unlike other upper moon demons, who show no hate toward who they fight(except the uppermoon 6,5,4), he has a really strong despise(jealousy) toward someone he fights. Something only humans are capable of doing so. No monster would do this. Also it shows that jealousy also makes demon weaker (Kokushibo).

Overall, Kaigaku is just a really unlucky person who never found a person who appreciated only him. Not together with someone else. His lack of empathy might have also come from the lack of appreciativeness.
