Well, he has to at least try within the limits of his morality. Going with the flow would also mean going against his own goals, so at least with this, he's not a complete doormat.
The consequence of going against this trope is that it won't do him any favors if any ambitious and/or powerful people learn about him. He would have people following him around - either wanting him to help usurp a king or start a revolution, or it would be assassins sent by men who fear his power...
...or he would end up tying himself down with some country one way or another.
