Jekyll's evil dimension took the form of Edward Hyde, a man who committed any number of crimes and performed acts of sexual perversion; seemingly, his most serious crime is the vicious murder of Sir Danvers Carew, a Member of Parliament.
Jekyll's fascination with his "other" self became so obsessive that he was finally no longer able to control the metamorphosis process, and Edward Hyde began appearing whenever he wanted to — and not at the command of Dr. Jekyll. Jekyll became, therefore, a frightened recluse, trying desperately to control Hyde, but successively failing, especially whenever he would doze off. Finally, crazed by anxiety and a lack of sleep, he hears Utterson and Poole, his butler, breaking down his private study door and, in desperation, he commits suicide, but just as he loses consciousness, Hyde appears, and it is the writhing body of the dying Hyde which Utterson and Poole discover.
