Earlier quoted context omitted.
They died, but they were indeed not killed. You may say something flowery like "the diseases killed them", or "the arrival of the Brits killed them", but the British empire or its subjects did not kill the vast, vast majority of Native North Americans who died as a consequence of their arrival.
They were killed by what the settlers brought with them. No, it was not deliberate (#), but nevertheless, their arrival is what killed most of the natives. (#) Obviously the settlers would have preferred to keep the natives alive since then they would not have needed to ship vast quantities of Africans across the ocean to enslave, but could have just done that with the locals.
That's all I meant to clarify. You'd be surprised how many people today actually think that the native population was wiped out through deliberate and intentional action. Your wording made it seem you believed that as well, but that seemed to not be the case.
>Obviously the settlers would have preferred to keep the natives alive since then they would not have needed to ship vast quantities
That's a caricature.
