I have a soft spot for Kudo. He's an old man living in a world that has left him behind, and he feels like a nuisance to his family. It's made him very bitter, but he's secretly terrified of being useless, so he's desperate to prove he can still do something of value, which results in the mess he makes in 3-3.
