Jekyll did and also made people think about whether Dr. Jekyll should be guilty for what Mr. Hyde did. The story of Dr. Jekyll and Mr. Hyde ended with Dr. Jekyll's suicide and confession. He admitted what he and Mr Hyde had done. He feels guilty and therefore chose to end the lives of both Jekyll and Hyde. However, this also warns that a person with dual personalities should be guilty of what his other personalities have done. The person should certainly be guilty if he is aware that he has done something wrong, but the problem is what happens if he is not aware of the existence of another personality and that personality is doing something crazy. Dissociative identity disorder (DID) is an example of split personality. There are two famous criminals who suffered from this mental disorder. One of them is Billy Milligan, who has 24 personalities, while the other is Juanita Maxwell, who has 6 personalities. Billy's personalities are involved in the rape and kidnapping while Juanita is involved in the murder (Grimminck, 2015). It has been argued that it is rarely successful for a person to use multiple personalities as a defense against insanity (Farrell, 2011). However, Billy Milligan is an exceptional case as he is the first American found not guilty due to dissociative identity disorder (Grimminck, 2015). The example of sentencing that is given to criminals suffering from DID indicates that they are guilty of whatever they have done, regardless of the personality who committed the crime. Therefore, even if Dr. Jekyll is not dead, he will still be guilty of whatever Edward Hyde has
