John Allen Chau was a fanatical missionary, desperate to force Christianity on the people of Sentinel Island. He ignored the laws of
India which protect the Native People. He also didn't seem to care that he might spread disease among them. For their part the Sentinelese did not want to be violent with him. These expert hunters fired arrows that missed him, to say:; "We don't want what you're selling; please leave us alone." Though he invaded their island repeatedly, they forgave him 3
times. The 4th time they saw that they would
never be rid of him & did what they had to do.
