Klaus is a very wicked individual. He is the devil in compared to the other "bad" characters in both programs. The others, at the very least, apologized and expressed sorrow and remorse for their actions. However, not only does Klaus not seem to care, but he also seemed to enjoy every single moment of his crimes. When it comes to love, Klaus has never experienced it himself. He assumes that everyone else is in love with him or hates him because they can't stand his power and influence. He uses this to justify any action he takes, whether it be against friends, family, or even people he doesn't know. He is the most dangerous out of all the characters because not only does he have no soul, but he also has no heart. Meaning that nothing could stop him from continuing with his evil deeds forever. However, despite all this, Klaus is still considered one of the best characters on television. This is because he is greatly developed through the eyes of each character who encounters him. Even though he is pure evil, you learn to like some aspects of his personality such as his design or his fashion sense. Furthermore, he gets better as time goes by.
