Yeah but the good part about him was that he wasn't misunderstood, he was completely evil, and not just comic evil. Totally completely evil, he saw the benefit to leaving Hiccup alive after killing Stoick, that's the point where you'd expect your average movie villain to go back disappointed and try and destroy the hero. His purpose was nothing but making the worst worse, he basically took any opportunity to completely ruin Hiccup, and the fact that he laughed off knowing the damage he'd done; he made an effort to display power and his view that Hiccup was worthless.

What you're looking at was the whole reason he didn't need to be special or super powerful, his evilness extended more than just blowing stuff up, he psychologically tried to ruin Hiccup as much as possible AND still achieve his evil goals. Which makes us hate him more, as we're supposed to.
