I think a part of Dean's character is to act a bit inappropriately. He lacks the modesty one can often see in Sam, or Bobby, or Castiel. Unlike some people, if not most, Dean has the luck of avoiding death every time he talks ill about someone more powerful when they're in the same room.

As for the priest, I knew from the moment he said those words that he just sealed his fate. You can't blame him though, I mean, who would have thought a brunette dressed in black was the very definition of darkness itself?

I also think Amara took his soul because she was still hungry for knowledge and power.
