How and why does Samuel Beckett create hopeless situations that parody reality in the play 'Waiting for Godot'?

Beckett talks about the theme of suicide consistently throughout the play, as the characters mull over their lives and existences. When Vladimir asks ‘What do we do now?’, Estragon replies quite casually ‘What about hanging ourselves?’ as a way of getting ‘an erection!’. The idea of getting an erection really seems to excite Estragon because it seems to be a way to escape the cyclical lull of boredom in which they have fallen as they sit waiting day after day for Godot, who never comes. Despite this, neither man is capable of actually following through with any plans that they make as they do not have any sense of certainty about anything that either one says, evident due to the fact that they seek for constant reassurance from each other. The play therefore essentially parodies the meaningless of the lives of these men and how they are so lost in their own existence that death seems more meaningful to them than staying alive. The concept behind this is existential nihilism which is a philosophical concept that life has no intrinsic meaning or value. For the population of Europe after the second World War, this concept may have been all too prevalent in everyones minds as they struggled to get over loss of loved ones and nice again find a reason to keep on living after such a harsh blow.
