Even Christians have different beliefs among denominations.
For example, the Church of Jesus Christ and the Latter-Day Saints (Mormons) do not believe in the Trinity (they believe that God, Jesus, and Holy Spirit are three different beings) and they do not believe in the divinity of Jesus Christ. Therefore, they are considered as a cult, or those who do go against the main beliefs of Christianity. and yes, they will go to hell.
The reason for the fights between Catholics and Protestants? The Pope.
Protestants believe in no superior figure than God himself, but the Catholics believe in the Pope as a supremacy among the humans, although lower than God.
-------------------------
Because it is a proselytising religion, Christianity is almost inevitably in conflict with other religions. Perhaps the one branch of Christianity that was capable of working amicably alongside missionaries from other religions was Nestorianism, which evolved outside the influence of the Roman Empire.
Philip Jenkins (The Lost History of Christianity) records that in 782, the Indian Buddhist missionary Prajna arrived in the Chinese imperial capital, Chang'an, but was unable to translate the Sanskrit sutras he had brought with him into either Chinese or any other familiar language. He contacted the local bishop, whose name headed the list on a Nestorian monument. This bishop had already translated parts of The Bible into Chinese, and the two probably shared a knowledge of Persian. Buddhist and Nestorian scholars worked amiably together for some years to translate seven copious volumes of Buddhist wisdom.

If you're talking not about sects but about the essential tenets: unless you're extremely selective about which verses you believe and which you don't, Christianity strongly conflicts with other religions. The Gospels are pretty clear that Jesus claimed not simply to be a way, but the only way, that man could come to God. If you believe that, then you're more or less forced to conclude that any other religion is... at best... beside the point, and more likely actually detrimental. This opinion tends not to go over real well with people following other religions.
Not particularly, "I am the way the truth and the life" John 14 is said by Jesus, it is taken correctly to mean that Jesus is the only way men can be saved from their sin. It is also the only religion that declares Jesus to be fully God and Fully man the second person of a triune God. The scripture quote above also eliminates christianity from the universalist message of all ways leading to heaven. Other religions erroneously call Jesus a good teacher like the dalai lama, or a good prophet like mohammed. neither of these can be held to with reason. to quote C.S. Lewis "You can shut Him up for a fool, spit at Him and kill Him as a Demon, or fall at His feet and worship Him as Lord and God. But let us not come with any patronizing nonsense about His being a great human teacher. He has not left that open to us, He did not intend to."(Fount 1952, C.S. Lewis, Mere Christianity p.52)

These religions have been in conflict because of the nature of monotheism and exclusivity. In monotheism, there is a singular truth and those who fail to agree are heretics and heathens. This view has prevailed through most of history, resulting in conflict, segregation, and apartheid between the religions.
During the middle Ages, the two primary religions in conflict during the Crusades were Christianity and Islam. Forces from each side fought for many reasons, and many of them religious: each side wished to influence the other on behalf of their own religious convictions.
