I think anyone who has sat through enough easter/palm sunday services has wondered how Judas could be such a bad guy. Supposedly Jesus had to die to provide salvation, and Judas made that possible.

The curse part is pretty obvious. I mean come on, he killed Jesus! ;) Of course people are going to curse him for it. Just like Cain was cursed for killing Able

I thought it was interesting that the National Geographic channel was airing the documentary all day on Palm Sunday (or at least much of the afternoon/evening). Probably just a coincidence...
