Klaus's anger on Elijah is very lame! Clearly all good things that Elijah has done for him totally out weights one betrayal! I get if he blames Mikael and Esther for ruining him but he is pathetic if he blames his siblings too for ruining him! Elijah stood by him all these years, tolerated his tantrums and all his revenge plans but clearly one reasonable betrayal outweights everything for this man! Klaus should realize if today he blames everyone for what he has become then tomorrow his own daughter will blame him for whatever she becomes!
Klaus should recall that every time he has been on brink of death or defeat is when Elijah stood against him! If he makes the mistake of turning absolutely against Elijah then he will be the only one to fall!
