Provoker

A Provoker is a villain who has wronged the hero so badly that it makes a more personal rivalry between them. The hero would act rage to stop this villain and not just for defensive purpose.

This could also applty to heroes as well. For obvious reasons, some may qualify as Pure Good so long as they don't go out of their way antagonize others in a more unnecessary and/or arrogant way. Many have qualified due to still showcasing almost exclusively positive traits, and are only provokers due to the fact their actions and opposition have affected their nemesis in a negative and/or inconvenient way.
