First, he proposes sending some people to their death. I mean, seriously, do you expect to find anything but death on Mars with our current level of technology if you can't come back?
Second, he's trying to convince people and the passangers/lemmings of the proposed expedition that's it's not actually sending them to death by fake science. Anyone familiar the very basics of statistics knows that you can't talk about 'life expectancy' of four people. And living in (yet to be discovered) lava tubes? Is that his plan?
And last, he wants to broadcast the agonizing death of these people worldwide. Am I the only one who thinks that this is, at very least, questionable morals?
