Whats important to remember about the native american tribes was that each tribe was wholly different from the other, which is why they were different tribes. One tribe would greet you and be friendly, offering to trade as a sign of peaceful intent. Another could attack you on sight as a show of force.

and to turn the situation on its head, the peaceful tribe could secretly have been surveying your defenses for weaknesses and strengths in preparation for a future raid, whilst the aggressive tribe, having shown its dominance through force, is more keen on a diplomatic exchange now that it knows that you pose little threat with your meagre force.
and all of this is without going into the politics and behaviours of individual european groups of settlers.
this is why diplomacy between european settlers and native americans, outside of already existing ethnic, cultural and religious tensions, was so finicky and weird.

so the often gross generalizations that either claim that the two groups were either peaceful and loving or hostile and brutal are very counter-productive in producing an accurate re-telling of events.
did Native american tribes provide food and medicine to sick and dying settlers? certainly.
did native american war parties butcher women and children? certainly.
did the settlers do the same? sometimes butcher, sometimes aid? certainly.

its reminiscient of the portrayals of the viking invasion of the british isles, into the lands of anglo-saxons.
popular depictions portray it as a naval invasion, where the vikings drove their ships ashore, leaped off and began to burn and pillage until half of the island was theirs. in reality there were politics, alliances, mutual aid and, more often than not, mutual enemies. Saxon kings provided viking allies with horses as they directed them to attack their saxon rivals.
At least in the case of the vikings they were indeed warriors, whereas most of the puritans were probably not even trained when it came to being hunters, even less so in the ways of actual warfare.
