Let's get this out of the way first: Klaus is not Angel. As tempting as it is to compare the two vampires, Angel on Buffy was — for the most part — a sensitive, kindhearted soul. When he was Angelus, he did his share of damage, but his default state was as a force of good. Klaus, on the other hand, is always kind of evil. While he has his own set of morals, they often involve killing innocent people. (Case in point: drowning Tyler's mom just to avenge Tyler's slight against him.) At the same time, The Originals is exploring a different side of Klaus. If he can't be good, can he at least be someone we root for? Angel, too, had to deal with the darker elements of his personality throughout the course of his spin-off. It's not about being a hero or a villain but rather finding a balance. Audiences love a complicated protagonist.
