I do understand what you are saying, but think about it this way:
I don't know if you played the first Witcher, but one of best features of Witcher was that a lot of the choices you made didn't have immediate repercussions on the story, nor it was clear how they were going to affect the story, or even if they were going to affect the story at all. If we translate this to the dragon in W2, you do have options with immediate consequences depending which patch you took in game, and you also have options which may or may not affect the story, which in this case, being that the event occurred at the end of the game, we would be talking about the next installment of the franchise.
And even walking away, one could argue that, in fact, one made a clear decision: leaving the dragon to its fate, whatever that fate may be.
W2 not as much as W1, but the game really isn't about black and white, is much more about grey. Personally, I love that aspect of the game.
Yes, I do have W1 and beat it. Yes, I realize that both games are about shades of grey and I think that's cool. No, none of that makes the situation with not knowing that a dragon in the witcher universe can survive something like that ok.
This is now dragging on to the point of rediculousness. This is not the topic of the thread. I was just making a small comment with my opinion in it and it has now taken over the thread. Let's try and get this thing back on track.
