How were the political structures of the Jamestown and Plymouth colonies different?

Basically both these regions, Plymouth and Jamestown had their locals as Indians. The differences, however, were those of the people who later on came to the region. In Jamestown, it was Europeans and in Plymouth it was Pilgrims. In Jamestown the conflicts were on the economical issue while in Plymouth, it were on economy and religion as well. In Jamestown, the Europeans were dependant on Indians because they could not cultivate land whereas in Plymouth, the Pilgrims were not dependant on Indians since they could cultivate the land. In Jamestown, there was no killing or barbarism whatsoever since the Indians were so generous and even though Europeans hated them, still there was no such thing. In Plymouth, the Pilgrims killed Indians for various reasons and enjoyed the fact they were slowly taking over the whole region with their power. There was a time when a disease badly hit the Indians of Plymouth and because their state was already low, they faced a lot of problems at that time.
