Looking at the wiki page, it seems the population on the island is decreasing. Hopefully they will either all die, thus relieving us of the ethical dilemma, or India will come to its senses and stop the abuse of these poor people and actually help them. Its criminal that they are allowed to carry on without access to any of the modern world's technology or services. And of course the islanders that killed those fishermen should also be forcibly removed and punished - murder is murder, and the fact that someone is pretending they are still in the stone age has never been a recognised defense...
