Well, I know Dean was just taunting Sam. But I was saying that the demon killing knife wouldn't have done anything to Dean, and they both knew that. Why was Dean all like "do it? kill me?" when Sam didn't even have the ability to kill him
Huh, you know, I think they knew the demon knife would at least hurt Dean.
And you are also right that it probably wouldn’t have killed Dean. I mean, he recovered from an angel blade through the heart, and angel blades seem to be a lot more “killy” than the demon knife. :P
But again, like I said in the other post about it here was that the entire scene was about Dean taunting and tormenting Sam anyway. Because demon.
Regardless of the potential effectiveness of Sam’s weapon (whether or not it could’ve hurt Dean), is really irrelevant to the fact that Dean was basically playing a cruel game of cat and mouse with Sam.
Again, because demon.
