Dr. Jekyll never realizes true right or wrong?

Answer 1

Essentially that is true. the actual motives for Jekyll"s experimentation may have been a sordid commentary on the up-and-coming vice of , you guessed it, Drug abuse. it was thought in the novel or movie version ( not sure which) the Doctor assumed his intellectual powers could control the baser impulses of Mr. Hyde- when the personalities were split. the split personality idea has become a staple of psychological sci-fi- admittedly not appealing to everybody and even Star Trek used the device on oc casion. In the Hyde case, the bad guy persona carried the day- in the end Jekyll committed suicide to prevent further incidents, as it were.
