The Bible itself agrees with you. Morality also arises from our conscience. Hindus won't be condemned because of what the Bible says. Hindus will be condemned because they did things they knew were wrong.
Those that never did anything against their conscience will not be condemned. Unfortunately, God who knows the future, has already weighed in, that none of us achieve that.
Oh, indeed. Torquemada, for example, wasn't doing anything against his conscience. Neither was Hitler, or Stalin, or Mao. The all thought they were doing the most honorable thing they could with the challenges and limitations they were faced with. As a christian religeous argument about morality, this seems pretty much out on the ragged edge of bizarre.
