So say you and a group of survivors ventured deep into forests of say South America or Asia in your efforts to escape zpaw. Miles and miles away from any semblance of civilization, you discover a tribe/colony of (apparently) unifected humans who have had no contact with the rest of the world for the past 100s of years. They are primitive people with no modern technology what so ever. Their colony is very well sustained.
What would you do?
How would you react?
Kill them all or befriend them?
