With the Indians they lived 1 way forever and the pilgrims thought it was the work of the devil, so the devil must be killed.in some cases they just thought they were different and where worried anyway, so it often lead to war.

Pilgrim: they had their own beliefs. For example, Squanto already had a full fledged belief system, as did his people, and he was not happy about being asked to chuck it out and believe something that was completely alien to his culture. Others who came into the colony – for example, trappers, hunters, traders, came from different backgrounds and had either their own religions (often Catholic, Protestant, Lutheran) or didn’t have any particular beliefs. None of these people were especially interested in adopting the Puritan beliefs – although a few young men did, solely so they could woo and win some of the Puritan daughters. Women were in short supply in colonial days and on the frontier in general, and young men would go to extraordinary lengths for them.

So the natives might not like them much.
