Augustus Caesar issued a proclamation that all the world should be taxed. Because of his decree, Mary and Joseph left their home and went to Bethlehem, where Jesus Christ was born. Birth in Bethlehem was a prophetic requirement for the Messiah. Without Augustus' decree, there probably would have been some other reason for them to go to Bethlehem, but none so historical and capable of confirmation.
At His death, Jesus was reluctantly crucified by the Romans. If He hadn't been crucified, most of Psalms 22 would be meaningless. If He hadn't died and bled, there would have been no efficacious atonement for our sin. Without a death, there would have been no resurrection.
Before He ascended, Jesus directed His followers to go into all the world and preach the gospel. The Romans had preceded them and had built great roads to all the important centers in their empire.
The Romans persecuted Christians for their refusal to acknowledge Caesar as god. To avoid persecution, the Christians left their homes and literally went into all the world. You might say the Roman Empire helped the Christians get out of their comfort zones.
The Roman Empire persecuted Christians and killed many of us. In the persecutions, many martyrs were made, contributing to our rich heritage and giving us their example of how to stand up to government and at the same time stand up for Christ.
This is a short list, but the question needed someone to get the ball rolling. Thanks to you, and thanks to the Roman Empire!
The fourth century Christian emperors contributed to Christianity by giving the new faith state patronage, providing generous state funds for the Church and persecuting the pagan temples, then finally declaring Christianity to be the state religion.
Christianity changed the religious map of the Roman Empire. It became the religion of the masses and it was then endorsed by the rulers. It led to the building of Christian churches, the end of pagan sacrifices and the introduction of the notion of charity. It led to the laying of the foundations of Catholic and Orthodox theology and scholarship. It also gave the peoples of the empire a new sense of unity and cohesion
Christianity
Christianity did not contribute to the fall of the western part of the Roman Empire. This part of the empire fell under the weight of the invasions by the Germanic peoples. The eastern part of the Roman Empire, which was also Christian, was not affected by these invasions and continued to exist for nearly 1,000 years. Pagan Romans thought that Christianity had weakened the empire by weakening the fighting spirit of the Romans. This view was incorrect and was a reflection of prejudice.
There was only one Roman Empire. Moreover, the Roman Empire did not study Christianity. An empire cannot study. The Roman Empire was where Christianity spread from Judea (which was a part of the Roman province of Syria). Both Catholic and Orthodox Christianity developed in the Roman Empire. Originally the were called Latin or Western Christianity and Greek or Eastern Christianity respectively. The former was the dominant form of Christianity in the western part of the Roman Empire and the latter was the dominant form of Christianity in the eastern part of this empire. There were also dissident Christian doctrines and sects.
The emperor Theodosius I declared Christianity to be the official religion of the Roman empire. In fact, he made Christianity mandatory for all.
Christianity did not easily spread through the Roman Empire. See the related question, "How did Christianity spread throughout the Roman Empire?"
The Romans who remained pagans did not contribute to the spread of Christianity Neither did Julian, who was the only pagan emperor in the Later Roman Empire

You need to specify what the following factors are if you want to make it possible to answer your question.
After the Emperor Constantine converted to Christianity, that became the official religion of the Roman Empire.
The Roman Empire made Christianity the official religion of the Empire, and 'encouraged' the peoples it conquered to convert.
One factor that did not contribute to the fall of the Roman Empire was Christianity. Some pagan Romans thought that Christianity had weakened the empire by eroding the fighting fibre of the Romans. This was not the case. When the roman state recognised Christianity, the empire regained political stability and attained a sense of religious unity among the majority of the population of the empire, which was Christian. The Great Persecution of the Christians unleashed by emperor Diocletian in 303 created widespread social unrest which was destabilising for the empire. This led Galerius, an emperor who took part in the Great Persecution, to issue his Edict of Toleration (of Christianity) in 311 to restore the stability of the empire.
