Morality should work something like this:
I won't murder you, because I don't want you to murder me.
I won't steal from you, because I don't want you to steal from me. etc etc
It's all to do with the interactions of people, and making sure we can get along together. One man living alone on an island has no need of a moral code.
If you and a group of people go an live on an island and decide what rules you do and don't obey, then they would probably be similar to those above, plus a fair few more.
I'd say it is arbitrary, but if you repeated this experiment a fair few times, the rules would probably be very similar. (The exception being if you put a few hardcore Christians/Jews/Muslims etc onto the island)*
* That would make a great TV show, until they all abandoned the don't murder rule on day 2.
