Hazard will miss Belgium's clash with Wales after helping his country qualify for the World Cup with victory over Estonia.
He is now back with Real Madrid and Benteke says the decision is one Belgium's players understands.
He said: "Today Eden Hazard is a different player because he has a history of injuries. He learns things and tries to avoid contact, even if his game requires it.
"But he shows intelligence in what he can do better. He is still a human being who tries to avoid take hits because there are pains that remain and unconsciously, you think about it.
"The Eden that dribbled five or six men is over. But the fact that he no longer does it does not mean that it will not be decisive."
