What if the "oceanic 6" all took a life on the island?
That would mean that Hurley and Jack have yet to kill someone. Perhaps that is why Hurley regrets going with Locke -- he ends up taking a life because of it.

If this premis is true, who *could* the others of the six be?
Michael?
Sun?
Sawyer?
Juliet?
Locke?
Desmond?
Sayid?
Jin?
...Okay who hasn't killed someone on the island?:eek2:

Hurley and Jack have taken lives...Hurley with his van and Jack with the Marshall. If you count killing others, you could lump in Bernard. Certainly more than 6...

There are a couple of places in Lostpedia with pretty comprehensive lists:

http://www.lostpedia.com/wiki/Life_and_death
... has a chronological listing, followed by a table-format summary.

http://www.lostpedia.com/wiki/Crimes_of_the_Islanders
... includes more crimes, including "attempted murder" (eg. Jack's *intent* clearly was to kill Locke) & Ben's "conspiracy" crimes (eg. ordering murder.).
