America founded on Christianity?

Whoever they were, broke biblical religious commandments and committed acts of the seven deadly sins by slaughtering and stealing Indigenous peoples lands by there excessive greed for gold. Then burning or drowning innocent women who were d at the stake or tying a rock around their neck and drowning them calling them witches to hide their shame. Then using Africans slaves to beat and whip and treating them no better than animals to work on stolen land. Is this the good Christian behavior the USA is founded on.
