What responsibilities does a creator have to his creation?

I just got done reading "Frankenstein"...possibly my favorite book ever...and it deals with this particular question. So how about it, what should a creator do for his creation? Especially when said creation is a thinking being. Is the creator responsible for its happiness, health, and general well being? Should a created being revere its creator merely because he created it? Is it the creator's fault if the being is imperfect and inclined toward evil?
