Despite Klaus being a very cruel and ruthless character, many people have come to love him because of Morgan's brilliant acting. Morgan's ability to express emotions brought a welcome complexity to the character, making us feel and empathize for Klaus, despite all the evil things he had done. Without Morgan's raw acting talent, Klaus would just be another black-and-white villain. In fact, executive producer and writer Julie Plec admitted in an interview with TVLine that Klaus was intended to die in season three of The Vampire Diaries, but Morgan's performance is a big part of what changed their minds.
