Castiel chased down every one of Raphael's followers. He didn't just wave his hand and kill them all. Amara was affected by the combined attack of Witches, Demons, and Angels. (For the record, this kind of question is why I think either you guys didn't really watch the episode all the way to the end, or you're purposefully ignoring major details from it and the series)

Which being showed the ability to smite every Angel in Heaven with a wave of their hand? Or smite every demon with a wave of their hand? Simultaneously, I mean. One-on-one, Amara did that as well. She did it to Lucifer, an Archangel, who was scared of a dozen angels (numbers do matter - you can't defend yourself against every attack) and overpowered Crowley before she was at full power.

No idea what the logic behind your "soul math" is supposed to be.
