The Strange Case of Dr. Jekyll and Mr. Hyde

Does Dr. Jekyll wish to control his darker side? Explain with evidence from the book.

Although Dr. Jekyll is, at first, fascinated with the idea of man being a combination of both good and evil.  After he has created the potion that can release th evil side, Mr. Hyde, Dr. Jekyll becomes desperate to control the decadent, murderous side of his nature. After the murder, in Chapter 4 Dr. Jekyll swears to Mr. Utterson that he is done with Mr. Hyde. 

"No," said the other.  "I cannot say that I care what becomes
of Hyde; I am quite done with him.  I was thinking of my own
character, which this hateful business has rather exposed." (Stevenson)

In Chapter 6, the author tells us that Dr. Jekyll seems to be rid of Hyde, his good health and happiness return, he is once more a social person. 

"The death of Sir Danvers was, to his way of
thinking, more than paid for by the disappearance of Mr. Hyde.
Now that that evil influence had been withdrawn, a new life began
for Dr. Jekyll. " (Stevenson)
   

Yes, I believe that Dr. Jekyll wanted to control his other side, Mr. Hyde, and he was able to do so for some time; however, as time went on, he didn't need to consume the formula to become Mr. Hyde.  He had lost the control that he wanted to have!  Mr. Hyde was overtaking Dr. Jekyll, and Dr. Jekyll realized that this was a horrible situation to be in.  He realized that he had to ride himself of Mr. Hyde or he would be forever doomed.  

Absolutely!  Just as he created a potion through experimentation to release the evil side of his nature, Dr. Jekyll is attempting to create an antidote which would prevent this side from getting out of control and possibly to prevent Mr. Hyde's appearance at all.  As Mr. Hyde becomes more powerful and consumes Dr. Jekyll's body more and more often, Dr. Jekyll realizes the seriousness of the situation and knows that he must make a desperate attempt to correct the problem.
