What's interesting to 'Vikings' the series is that Horik is so blind in his greed and his desire for revenge that he can't hear reason, and he's probably so insecure about Ragnar that he won't take his advice. And straight up, honestly, if you ever have to say to someone, 'Hey, remember, I'm the king?' It's too late, and you've lost your authority.
