Would you believe if someone had two egos from one person? Even that two egos are of the opposite. Good-natured Doctor during the day, however at night he became a bad criminal. Dr.Jekyll was efforted to separate good from evil. He made a madecine but it was not a success. For test Dr.Jekyll drink it and had two egos from one person. At night he turns into a terrible criminal who frightens a child and even kills an old man. Eventually, he gets chased by the police. Many sufferings intersect and eventually end up dying on one's. Dr.Jekyll doesn't have a bad intention but his desire for research led to the incident. Maybe thist story is not a common story but I wish this doesn't come true.
