I’m done for

A shipwreck survivor washes up on the beach of an island and is immediately surrounded by a group of native warriors.
“I’m done for”, the man cries in despair.
“No you are not,” comes a booming voice from the heavens. “Listen carefully, and do exactly as I say. Grab the spear from the one who is beside you and shove it through the heart of the chief.”
The man does so, and the remainder of the band stare in disbelief.
“Now, what?” the man asks the heavens.
“Now, you are done for.”
