Theme of Responsibility

I think when Mary Shelley wrote Frankenstein she wanted to reveal and show the world that some things we do, we don't plan ahead on the next steps enough and we just drop the responsibility and move on with life, and sometimes this comes back to haunt us. In this novel she reveals clearly that Victor had absolutely no idea what he was doing, even though he had planned how to create life for a long time. He does not accept responsibility for the creature and therefore it comes back to bite him. Sometimes in life we have to accept responsibility for our actions. Sometimes this is hard... As it is in the novel. Have you ever been in this situation? How can you be able to take the responsibility for ALL of your actions even when you mess up?
