When is invading an inhabited space any different to home invasion. I am sure many of the individuals who are horrified would have raised their rifle to the maniac bursting through their front door. Seems the same deal to me!

Sad but a risk they take

It's all very tragic, regardless of perspective.

I think there has to be a distinction made here between the deaths of Treadwell and McCandless and that of Chau. Chau was definitely in the grip of religious delusion and was a on a personal crusade to convert “savages”, and his arrogance and persistence in face of warnings not to try to land on these Islands in the Andaman Sea, because the Sentinelese natives did not want any outsiders on their island, caused his own death. The Indian government has made it very clear to all those navigating in this area not to approach these islands. How supremely arrogant for John Chau to think his god was going to protect him from harm and that these people needed to be converted! I have no sympathy at all for him, but the other two are quite tragic, especially Chris McCandless who seemed to turn increasingly into a loner and probably had mental health problems, not looking after his own welfare and nourishment indicates this. Timothy Treadwell loved and enjoyed studying the bears and I’m sure he knew the risks involved, so in a way ...just like any other high risk occupation, he took a calculated risk to do something he wanted to do. Unfortunate that his girlfriend also lost her life, but I’m sure she was there with him of her own free will, so a double tragedy.

Delusional is a good word. Maybe some denial.
