Imagine that there's a tribe of about 100 people living isolated. None of them know about Christianity or any type of religious concept. According to Christian doctrine, they will not be held accountable on judgment day because they never had the chance to believe.
Now, should a missionary even try to convert any of this tribe? If he spreads Christianity to them, let's say that half of the people will believe. That means half of them will be saved, and the other half will go to hell since they rejected Christianity's teaching. Doesn't this prove that it is better to keep people in ignorance of Christianity (so that they don't have to be accountable on judgment day), than to spread the religion and doom those who reject the faith?
