I would suggest that, in the beginning, the monster is the most innocent while Dr. Frankenstein does the most evil. I think that is, at least in part, the point the novel is making. The monster is only trying to survive. He is tossed out into the world alone. He knows nothing of the world. He does not even know language. In many ways, the monster is like a baby that is abandoned. Frankenstein created this monster and then he left it alone. Not only did he defile graves and commit terrible deals to make his monster, but he also lost all sight of whether or not he should because he was so obsessed with whether or not he could.
