I'm sorry, I do not understand your question in its entirety, but I did receive a similar question yesterday. Thus, I will repeat that answer here.....
Jekyll created Hyde with the distinct purpose of giving himself the ability to do what he inherently believed was wrong without the repurcussions. Whether you look at this as an example of good versus evil or morality versus immorality, Jekyll's intent was to free himself from responsibilty....... so, the main question would be, do you believe this experiment would be used to free oneself from the responsibility of doing good, and what purpose would that serve?
