It is seen through this soliloquy that Hamlet is a melancholic, depressed and suicidal. Hamlet is contemplating life here, and why he still is living. He is crazy here, not on purpose. This foreshadows the antic disposition that will happen later. Hamlets actor says this line using different tones of voice, slowing at times, and speeding up. This allows the viewers to understand he really is crazy, and that he either will seek revenge or kill himself.
