It seems like Robert Louis Stevenson, the author of <em>"The Strange Case of Dr. Jekyll and Mr. Hyde"</em> meant his story to be ambiguous in many ways, to frame the conflict between <em>"Good & Evil"</em>, thus he creates a moral paradox among <em>"Ethical Altruism"</em> and <em>"Ethical Egoism"</em>; ergo one could consider that final decision as both hasty and rational, since it came out of Dr. Jekyll's urgency and despair of preventing further damages, but it was thought-out as well, displaying a line of thinking typical of <em>"Ethical Altruism"</em>, which requires logical reasoning.
