Who cares if we can live to a thousand or a few hundred years. That guy is having a rush. Live while you can, and enjoy it. Helium rules!
Maybe it's something a teenager would do. When I was fourteen, I was aware of my own mortality, but I didn't care. Ballooning? Hell yeah!
But I certainly knew when I was doing something 'wrong'. Like murder? If you kill someone and are in your 'teens' and don't realize that it's wrong, then I don't know what to say. Being a teenager isn't an excuse.
Giving teenagers a 'blanc carte' to kill just because they're young and hormonily fucked up doesn't give them the right to murder.
And who wants someone like that living for a thousand years anyways? Castro? Hitler? I won't say the 'B' word, only four more years to go.
I think many kids have a good idea that murdering people is not quite accepted in our society. But then again, the current leader is doing it without recrimination on a mass scale. They're not allowed to vote or watch 'Saving Private Ryan', or watch porn, but it's okay to for their McFlippin Burger earned tax dollars to go to nuclear submarines, tomahawk missiles and bombs.
Might is right, just don't do it at home. No wonder they're confused.
Ahh, if only we directed them towards making us old fucks immortal, or learning the joys of floating over the Earth in a bunch of Helium balloons....
