Ordinarily I wouldn't stoop to such backwards behavior but as this is a religious forums, I will illustrate with, of all things, an example from my religion and hopefully roll high against instant credibility death.
Anyway...
The epic of greater India, the Mahabharata, is a story about an empire fractured and factioned between cousins finally brought to battle at Kurukshetra (lit. field of actions).
The leader of this tragic comedy, the person who brings this all about - a battle of cataclysmic proportions, is Krishna, considered as the incarnation of God, in order to turn the wheel of the age and set the course of all to come.
The centerpiece is considered almost a separate work - and indeed maybe it is; the Bhagavad Gita, which recounts the dialogue between Krishna and Arjuna, leading warrior of the 'good guy' cousins, the Pandavas. Krishna has decided not to take up arms, and instead drive Arjuna's chariot (considered a job far beneath a warrior, let alone king - Krishna's worldly status amongst his peers).
Before the commencement of the battle, the two armies are faced off against one another, each awaiting the blowing of the conches/horns that will signal the attack. Essentially waiting for the leaders to gather the resolve necessary; each facing the end of all things in a mad gambit for the throne they covet, knowing that what's about to begin will end in the death of millions on both sides, and more close to home - it is brother against brother, cousin against cousin, not just for the princelings but the common soldiers as well.
It's the end of the line, so to speak.
Arjuna asks Krishna to deliver him to the midmost point between the two armies, in the middle of the thrice empty field, by way of gaining a vantage to ponder his fate; what brought him to do this, that he now stands ready to slaughter his kin and burn the world.
He finds that he can't do it; he has worked diligently to bring this about, in accordance with his view of what is the right action, but now faced with the reality and enormity of his responsibility, he finds it repugnant - even abhorrent.
His weapons fall from his hands and he, nearly swooning at the prospect of his actions, resorts to Krishna for guidance.
The Bhagavad Gita then consists of Krishna reorienting Arjuna's perspective using every tool in the book - all 18 of them, including the now-famous quote by way of Oppenheimer:
"Behold, now I am become Death/Time, the destroyer of worlds" and showing Arjuna a terrible form of his which appeared to devour all the enemies now arrayed against him in its myriad maws.
He tells Arjuna that everyone on the field is already dead; he, Time, Death himself, has already killed them; Arjuna is merely the instrument; to cast off his uncertainty and act with clarity in motion, certain in the purpose and rightness of his mission.
Then the conches resound an the battle begins in earnest.
...Later in the battle he faces off against Bhishma, his grand uncle and the greatest warrior of the age who is on the wrong side for all the right reasons.
He finds that he is unable to fight Bhishma wholeheartedly, and suffers terribly at the edge of defeat under the unending rain of arrows flashed forth from Bhishma's thunderous chariot who is unrelenting in performing his own duty.
Krishna, becoming exasperated , jumps down from the chariot, and takes up a broken wheel to wield, moves towards Bhishma with death in his eyes - bending to the point of breaking his vow not to take up weapons.
Arjuna is at this point, terrified where he was earlier demoralized, fearing not for himself but for Krishna's vow broken on his behalf.
He jumps down and throws his arms around Krishna's feet to prevent him from doing so, and vowing to fight with renewed endeavor takes up arms again, redeemed in his resolve. (Bhishma is, meanwhile, greeting his death with palms folded, understanding the inner identity of Krishna).
Fear, love, example, and many more things mingled in a single motive intent.
History, legend, allegory; not all that important in the end; drink secret water from all tongues.
My bad for letting the camel's nose of religion into the tent y'all.
