Is "Waiting For Godot" A Pessimistic Text?

"Waiting for Godot" is not a simple play to read or watch. It has got number of implications at various levels and various forms. At one level, it becomes an optimistic play, though to a very little extent. The characters are basically waiting for Godot: hence, they have a hope. And they are standing there with a little optimism.
On the other hand we see a number of dialogues, in which we see the characters falling into despair and do not have any way out. We find "Nothing to be done" in the very first scene of the play and this dialogue is repeated time and again both by Vladimir and Estragon. This dialogue shows the level of disparity in which the characters are living. Similarly, the dialogue about the holy maps: "the dead sea. The very look of it made me thirsty. This is where we will go. We will be happy", also marks about the increasing anguish in the characters. The fact that they find happiness in death contributes to the pessimistic approach of the text.
In the same way, the Schopenhauerian concept of "existence itself is a crime" is referred to time and again. For example, in Act I, when the characters talk about repentance, one of them says, "our being born". This signifies the fact that they are resentful about their existence.
In this way, we can say that Waiting for Godot is more into pessimism.
