The death of hero/heroine may resulting the good side's darkest hour, as sometimes, this led to some of hero/heroine's ally choose to give up.

Some hero/heroine may able to revive him/herself through sheer force of will driven by his/her bond with others, but the others whom still have hpe of resusciation would need outside aid by their family, friends, and allies.
Of course, the villain whom killed them may not take this well, as the killed hero/heroine would brought disadvantages for their side or turned out to be the Chosen One, but whatever the case, they would do whatever it takes to prevent their revival. It's more than often that the hero/heroine would immediately defeated the said villain upon their revival, either the deed is done personally or through their most trusted ally/love interest. While the revival may led the hero/heroine had a second chance, they may also given the opportunity to passed their duty to others.

Inigo Montoya: He's dead. He can't talk.
Miracle Max: Whoo-hoo-hoo, look who knows so much. It just so happens that your friend here is only MOSTLY dead. There's a big difference between mostly dead and all dead. Mostly dead is slightly alive. With all dead, well, with all dead there's usually only one thing you can do.
Inigo Montoya: What's that?
Miracle Max: Go through his clothes and look for loose change.
