Why do you think that even American Indians who sought peace were attacked?

I'd say due to the pillaging of resources or capturing slaves. It could also be done as a warning to show no one was safe.

There are several reasons why even American Indians who sought peace were attacked by the new settlers. First of all, many attacks were due to the desire to drive American Indians out of their lands. This would allow the European settlers to keep the land for themselves. Moreover, another reason could be the fact that American Indians were discriminated against due to racist ideas of the time. This meant that settlers believed American Indians to be savage and uncivilized. Europeans believed that American Indians could attack at any time, and they preferred to be the first ones to do so.
