Is it a happy ending, in your opinion? Did it turn out okay?
If so, it will be Good Judgment, which means the Obtaining Goal could go either way (stop the curse, fulfill the curse). The success/failure doesn't matter as much as the judgment-feel of the end.
Does the reader say, "Oh, Good" or "Oh, Rats"?
When you select the Success/Failure option in Dramatica, other things get assigned. For example, the Signposts. Look at the signposts both ways to find out if your acts fit more in a "spin it fail" way or "spin it succeed" way. The success of the goal isn't as CRITICAL as the Judgment, because the goal can go positive or negative under the same category. Obtaining can be receiving or stop-from-receiving. Positive or Negative both are called by the same Goal name.
It doesn't matter if someone dies or not, the goal the protagonist is pursuing, personally, is what he's after. I want to stop someone from dying this time or I want someone to die this time. That would be the actual literal goal, the Protagonist's take on the goal, if I'm not mistaken.
If he's the minority, he may be considered the Antagonist, in which case, the goal OPPOSITE is what he’s after.
If the person who will die is saved from it, and the protagonist was working toward that, it's Success.
If the person who will die is saved from it, and the antagonist was wanting that, it's Failure.
If the person who will die is NOT saved from it, and the protagonist is disappointed, it's Failure
If the person who will die is NOT saved from it, and the antagonist is disappointed, it's Success.
