Blessing her should give her the possibility of a new path....
Anyway if she wants to die, she can simply cut her wrist...
Okay, to be clear, this is a video game made in the early 21st century, not a game which has traveled back in time from the 24th century. It was programmed by human beings, it is not managed by a highly advanced artificial intelligence which reacts to your every action on the fly. Each and every single action and reaction has to be programmed into the game by very very busy human programmers and scripters. That means that not every single possible interaction you can think of, for every possible scenario, is going to be present in the actual game.
Additionally, these are not actually real people, but artificial constructs. Casting a spell on them does not give them "the possibility of a new path", nor can they up and decide to spontaneously cut their wrists.
I feel that I have to mention this to you, so
