Answer:
Dr. Jekyll's research and experiment was morally questionable from the start.
Explanation:
Dr. Jekyll's research and experiment included creating a type of medicine that allowed him to separate the good from the bad and the dark. This is because this medicine allowed him to transform himself into a good citizen and into another citizen who only had malice in his personality and lived totally unscrupulous.
The problem with this experiment is that the doctor allowed a totally evil and unkindly circulation to circulate around the world, and he could do abominable things. This is morally questionable, even before that individual killed.
