The belief does not matter, it is about submission to your belief in a afterlife to be gained by following certain teachings -- racially, fighting, torture, love, tribalism etc.
The Basiji in Iran, founded in 1979 by the order of Ayatollah Khomeini, invoked the 680 Shia martyrdom to its "contemporary" Iran-Iraq war in the 1980s, it promoted and established "soldiers of God," carried out and instituted self-sacrifice which was accepted by at least 500,000 Iranian Shia Muslims ready for self infliction, it created child sacrifice, thousands of children, were sent out to clear the mines at the border with Iraq. Between 700,000-800,000 Basij volunteers were sent to the front during the eight-year Iran-Iraq War, when self-sacrifice was the quintessential value of the Islamic revolution, used as cannon fodder when the Islamic regime, often with a plastic "key to paradise" hanging around their necks and the promise that they would automatically go to paradise if they died in battle."
From a research on Child Soldiers: in 1984, Iranian President Ali-Akbar Rafsanjani declared that "all Iranians from 12 to 72 should volunteer for the Holy War." Thousands of children were pulled from schools, indoctrinated in the glory of martyrdom, and sent to the front lines only lightly armed with one or two grenades or a gun with one magazine of ammunition. Wearing keys around their necks (to signify their pending entrance into heaven), they were sent forward in the first waves of attacks to help clear paths through minefields with their bodies and overwhelm Iraqi defenses. Iran's spiritual leader at the time, Ayatollah Khomeini, delighted in the children's sacrifice and extolled that they were helping Iran to achieve "a situation which we cannot describe in any way except to say that it is a divine country."

Guibert de Nogent - The Deeds of God Through the Franks
''God ordained holy wars in our time, so that the knightly order and the erring mob, who, like their ancient pagan models, were engaged in mutual slaughter, might find new way of earning salvation. Thus, without having chosen (as is customary) a monastic life, without any religious committment, they were compelled to give up this world; free to continue their customary pursuits, nevertheless they earned some measure of God's grace by their own efforts. Therefore, we have seen nations, inspired by God, shut the doors of their hearts towards all kinds of needs and feelings, taking up exile beyond the Latin world, beyond the known limits of the entire world, in order to destroy the enemies of the name of Christ, with an eagerness greater than we have seen anyone show in hurrying to the the banquet table, or in celebrating a holiday. The most splendid honors, the castles and towns over which they held power, meant nothing to them; the most beautiful women were treated as though they were worthless dirt; pledges of domestic love, once more precious than any gem, were scorned. What no mortal could have compelled them to do by force, or persuade them to do by rhetoric, they were carried forward to do by the sudden insistence of their transformed minds. No priest in church had to urge people to this task, but one man urged another, both by speech and by example, proclaiming his determination, both at home and in the streets, to go on the expedition. Every man showed the same fervor; the chance to go on the trip appealed both to those who had little property, and to those whose vast possessions or stored-up treasures permitted them to take the richest provisions for the journey. You would have seen Solomon's words clearly put into action, "the locusts have no king, yet they march together in bands." This locust made no leap of good works, as long as he lay in the frozen torpor of deep sin, but when the heat of the sun of justice shone, he leaped forward in the flight of a double (or natural) movement, abandoning his paternal home and family, changing his behaviour to take on a sacred purpose. The locust had no king, because each faithful soul had no leader but God alone; certain that He is his companion in arms, he has no doubt that God goes before him. He rejoices to have undertaken the journey by the promptings of God's will, who will be his solace in tribulation. But what is it that drives a whole community unless it is that simplicity and unity which compels the hearts of so many people to desire one and the same thing?''
''The retreating Muslim army was met by the ferocious Arab women in the camps. Led by Hind, the Muslim women dismantled their tents and armed with tent poles charged at their husbands and fellow men singing an improvised song from the Battle of Uhud that then had been directed against the Muslims.
O you who run from a constant woman
Who has both beauty and virtue; And leave her to the infidel, The hated and evil infidel, To possess, disgrace and ruin.
This boiled the blood of the retreating Muslims so much that they returned to the battlefield.''
''After holding off the initial attacks by the Byzantines, the Muslim right wing fell back, followed by the right center. They were again said to have met by their own womenfolk who abused and shamed them.''
''Know you are fighting men who look into the barrel of your gun and see heaven, now how can you compete with that. We are promised victory and we will surely get it.” -Dzhokhar Tsarnaev
''I have fought in so many battles seeking martyrdom that there is no spot in my body left without a scar or a wound made by a spear or sword. And yet here I am, dying on my bed like an old camel. May the eyes of the cowards never rest.'' - Khalid Ibn Walid
''In order to capture, one must let loose.'' -Thirty-Six Stratagems ''He who finds his life will lose it, and he who loses his life for My sake will find it.'' -Matthew 10:39
''The Sword will hit the neck of he who cannot bow its proud neck -- being rigid is a weakness, the shadow that lies flat on the ground does not take a deathblow.'' -Rumi
Fear God above all so you will not fear earthly enemies and struggles.
Love God more than anything and anyone else, so you will not be distracted by the lesser love of those next to you.
Be willing to sacrifice all for God, so you will not attach to your belongings and material gain.
Submission is freedom -- the more a person think he is free, the more influenceable he is.
