If u read the novels , how klaus looks like?and is he evil?

I'm too lazy to dig up my book to tell Ты his looks, but I can answer the секунда part. Yes, he's evil. Way еще than TV!Klaus (who I no longer consider evil). Let's put it this way, one of his Цитаты is "I've walked with the devil." If Ты want еще I can give it, but I don't want to spoil anything. :)

In the novels he is еще seductive and evil but i forgot how he was described
