No, the seme is an ass. You can be an ass and not be a bad person. Guys do things like that because they are afraid to face their own feelings. It is a form of cowardice found largely in men. They cover up their "weak" (normal) feelings with aggression. I'm a guy and I catch myself doing this all the time. Seme is immature so he got really lucky.

... you do get you are talking about a male fictional character created by a woman who needs to publish her story based on something she fantasizes/fetishizes about, meaning nothing to do with male psychology but more about what she finds attractive, that has nothing to do with male morals and behavioral analysis whatsoever but a lot more with what her page limit and her editos' opinions are, right? Good.
And I am sure you also get your connection to this character as a fellow dude is purely subjective, just as my theory is.

So I do not know how a male fictional character written by a woman who based him on her fantasizing material can be objectively seen (and so concluded by a real life man at that) as "an ass". I'm just throwing my opinion as a fellow fan out there, making speculations is cool by me, and you made an interesting point, but you can't just conclude that "this is what it is I know because I am a guy". It doesn't work like that, especially in yaoiland, which is ruled by women.

I'm talking about it based on real people. I'm calculating by nature; I relate everything to the real world. This is no different. Considering how many people agree with me I wouldn't really say that my opinion is not widespread. I guess I never will understand a woman's fantasies ╮(￣▽￣)╭

lol women be scary creatures. Well if you put it like that I guess it is pretty natural for someone to relate what they read to the real world. It's just a matter of how distanced you can get from what you read. Maybe I put too much of a distance sometimes.
Have fun in yaoiland ~
