Final answer:
The police arriving on Christmas Eve signifies an emotional and symbolic event, mixing anticipation, relief, and thematic resonance with the holiday's focus on atonement and forgiveness.
Step-by-step explanation:
The significance of the police arriving on Christmas Eve to arrest the person in the given passage appears to hold different layers of meaning. Christmas Eve is traditionally a time of family, forgiveness, and reflection, making the arrest have a particular emotional weight. While the individual anticipated the arrest, there is also a sense of relief that may be tied to the timing, perhaps feeling that the arrest is a form of judgment or penance that fits with the spirit of the holiday. The notion of being grateful for a beating 'within an inch of his life' suggests a desire for punishment as a means of atonement, which resonates with the themes of sin and redemption often reflected upon during the Christmas season.
