Spicer is an ageing smalltime gangster, henchman to Pinkys gang.

Spicers function in the plot is experience to the gang he plays a vital part in the outcome of the movie. He is involved in the major turning point in the film. He is seen as the weak link in the gang which isn't worthy of being there. This leads to his death at the hands of Pinky.

The scene in which the character plays a key part is when Pinky pushes him through the banister because this shows Spicers fear of Pinky and this is when he realises in his eyes Pinky has control over him. When Pinky is talking to Spicer just before he pushes him you can sense worry in his voice indicating he is no longer cut out for the role of gangster.
