Christianity= the end of all peace?

do you think that if there never was christianity, we would have a peaceful world of undisturbed ancient religion and paganism. i mean, back then you pretty much just lived your whole life in peace, and died peacefully. then this forceful one God comes in and causes the world pain for thousands of years to come. now people are at each other's throats due to Jesus Christ and his holiness. if jesus never lived, we'd be better off
