What is Christianity impact on society?

It is not clear what you are asking, as this is not a question.

Christianity is relevant across all cultures. The death of Jesus as - "the lamb of God who takes away the sins of the world", John 1:29 - and the the gift of eternal life God offers is available to people of all tribes and nations.

Becoming a Christian does mean certain aspects of a person's culture will no longer be desirable for them. This applies to Western, Asian, Middle Eastern, or any culture.

For example for someone who lives in a culture where animal sacrifice is a way of appeasing spirits then the knowledge that comes with Christianity of who God is and His sovereignty over all His creation - spiritual and material - will have a liberating effect for that person.

John 8:32 you will know the truth, and the truth will set you free."
