Ok why the hell did Klaus keep the bodies of the other 5 Originals?Does he plan on becoming even Mehr 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 arsch way of protecting them. Cause after Mikael died, he sagte they were gonna have a 'family reunion.'

Klaus cares his family...

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