I want to call him a jerk, and he is, but it looks like he really does like Haruto to me. So, altho I don't ship them together, go for it!

Well, that it is wrong, it is wrong. But, looking from his point of view, I would say that it is better to try than to live wondering if he had a chance. He is a jerk indeed, but not a bitch who just want to fuck. I'd say that he should try it for his own sake, even tho I assume that he, himself, knows that he has already lost. He is not a bad character, so I can't just call names.

Nope. Trying and seeing if he had a chance would be to confess to him (and yes, maybe kiss him), but NOT to manipulate him into ending another relationship. There is NO excuse for that. NO REASON for that. He is being cruel and vindictive. That is NOT love. That is "I want what I want and will do anything to get it, no matter who else it hurts."
I say create a hell on that village so bad, but so bad, that they will wish they were dead.
