Craving Conflict

One example of a character experiencing a large amount of conflict is Dr. Frankenstein. What is strange about him is that his real conflict is his own success. He has spent years trying to develop a way to bring life to things that have stopped living. It is to the point where it takes up nearly all of his existence. Because of this one might believe that the conflict of the story would have something to do with his inability to make this possible. However, it is not until he does actually make this happen that the true story begins.
Dr. Frankenstein finally creates life when he brings his creature from the dead. Instead of rejoicing over his success and embracing the creature, he runs out of the room and hides from it, hallucinating in fear of its approach. He actually goes crazy from the creation, and avoids it for months (how long exactly I do not know, seeing as it was only an excerpt that we read). I can assume though, that the new conflict of the story becomes Dr. Frankenstein's hunt of the creature, and that it will only be resolved when he is once again dead.
I fear that Dr. Frankenstein will be in a sort of infinite state of conflict, because it is not as though he wanted any less to make his discovery, he simply realized the potentially awful effects of it. Therefore, he may never be happy, seeing as what he wants is evil, but evil is not something that he wishes to indulge in.

In a far less obvious way to the story, I think Brad from Algorithms for Love is another character that faces a lot of conflict. In along the same lines as Dr. Frankenstein, what he wants is to make his wife happy, but he knows that making her happy may be allowing her to do something crazy (such as creating the Aimee doll). In both cases these people can never 100% do what they want, because the block for their success is its own effects.
