What was Michael's plan in the beginning?

Betray and kill Trevor with the help of Dave? If not, I don't understand. Why Michael wanted to betray B and T?

Dave Norton was a rather new agent with no success to show.
He offered Michael a deal:
Michael betrays Brad and Trevor, so Dave can be the hero of the day and get promoted.
In return, Michael's death is fake, he gets put in an inoffical witness protection program, can keep the money and live a new, easy life with his family under a new name in LS.

Michael accepts the deal, because he feels that this is his only way out of a life of crime, to live with his wife and young children.

I highly suggest that, after you finished the game, you continue to hang out with the 3 main characters in all possible combinations - several times.
They will talk about the heist, but also start to ask about history and what happened in North Yankton and why.
Also, funny and quite surprising things.

I understand. Thanks. It's still a damn shame that Michael betrays T and B. After everything Trevor did for Michael, he helped Franklin to kill him without remorse... ;(

That's just one of the posibilities because Michael could be the guy that once betrayed and then does it again but that's just one option.
