Ah well, the thing is that the way you say it, "liking a character because of the actor playing him no matter how much of a jerk he is" implies that one likes the character because of the actor in spite of the character being a jerk... in my case, being the type of jerk that Hiroto is in and of itself actually a very very compelling reason to like the character.

I mean... Tsukasa? Is a dick, and I love him for it. Kitaoka? Is a narcissistic, hedonist douchebag, and probably my favorite rider character. Hajime? Ain't exactly sweetness and light. Yaguruma? Had a hell of a superiority complex as ZaBee and he didn't exactly turn into a nice person when he became KickHopper.

And the biggest, best example of them all? Atobe Keigo.

In conclusion? I like assholes \:D/
