Church Mission or Death Mission?

A man from Alabama, named John Allen Chau, has been killed by isolated tribespeople on the North Sentinel island between India and Myanmar. Chau was motivated to come in contact with these people in order to preach Christianity. He was illegally brought to the island by fishermen, where he kayaked to shore. There he was shot down by arrows. The fishermen watched from a distance as the body was pulled by rope, then decided to flee the scene. His body has still not been recovered.

Many are wondering if his remains should be recovered. Contact with the Sentinelese tribe is illegal due to their risk of disease from outsiders. It is even possible that they have already contracted a disease from Chau, such as the flu or measles, that they have no immunity to. The Sentinelese could be exterminated, because the hunter-gatherer tribe consist of only about 50 to 150 people in all. They live on their own small island, completely removed from the rest of the world. They do not welcome outside contact, and even shoot arrows at helicopters and boats that come too close to their shores. This tribe clearly wants to be left alone.
