been a while since i read frankenstien, but i seem to remember him as someone who was very unorthodox, lost in his search for the secrets to life.. I don't think he understood the true scope of what he was doing until he did it, he didn't understand the responsibilities one has when creating a living thing. And frankenstien's monster wasn't created evil, it was the people who portrayed him as some dangerous thing based upon his looks, and they outcasted him because they didn't want to understand him.
a good story..
