Ok why the hell did Klaus keep the bodies of the other 5 Originals?Does he plan on becoming even más powerful somehow through them?

I think Klaus has a sadistic solution to abandonment issues.

He cares for his family, and if they try to leave him, then he'd dagger them to keep them close to him. Look at what he did to Rebekah back in the 20s when she chose Stefan instead.

I also think that he really believed that Mikael was after all of them, and him dageering them and keeping them with him was his weird culo way of protecting them. Cause after Mikael died, he dicho they were gonna have a 'family reunion.'

Klaus cares his family...

Your pregunta is a little ambiguous. What exactly do tu mean when tu say that he 'keeps' five other Originals?
