Halo is love. Halo is life. We celebrate the Masterchief, we thank him for this, and not this.
Reasons to live imply teleology, but if there is any reason to live it is not for the reasons to live. That would make life so linear [like games], do this then do that, believe in this and achieve that etc. In the end its an empty game-world.
The best reason to live imho, is that there are no reasons, and especially no best reasons.
If God gave a reason it would make him idiotic. If there is no God its the same.
