I just spotted that I didn't answer this. Everyone has at least one bad day where they're an antagonist to someone else. In stories like this, it sometimes comes from an outside influence. In both cases, it's a temporary thing, rather than an indication of their overall character.

I think it's better to look at the story as a whole. If you've got a single movie or a single book, that's faster to figure out what kind of character they are. In a TV series or a large universe like Star Trek and Star Wars, you have to take into account all of what they appear in.
