I'm not sure if he'll hate him. If there's an arc for Haruka, I think it's more about him realizing that hero worship is stupid and that he should've stuck to his principles during the Prison break arc, instead of wanting to "meet his hero". As the saying goes, never meet your heroes.
He realized that the great Chainsaw Man that he idolized, was pretty much just a bit of a pitiful loser, not someone worth hailing as almost a demigod.
