If your talking about the X-Men Origins Deadpool then no. Although he is defeated by Wolverine and Sabertooth; even beheaded, he still lives. After the credits there like 3 extra endings. 1 is Colonel Striker walking along until his feet bleed. 2 is Wolverine at a bar in Japan. 3 is Deadpool's hand reaching out from the rubble and grabbing his own head. The head says "Ssshhh" which is either all it can say cause his mouth's sewn shut or its an example of Deadpool breaking the fourth wall.
