Poetry as horror

There’s a haiku-writing serial killer murdering the residents of a small Japanese town. His haiku, which he leaves at the scene of each crime, becomes incredibly terrifying in context:

Setting a fire– / smoke gives delight / to a country fellow

(I’m assuming there’s a dash or other punctuation after the first 5 syllables. Is it wrong that I’m thinking about the haiku poetics of a serial killer?)
