Although being emotionally hardened is essential to being a competent law enforcer, it is still touching to see how the Police of San Angeles Society has regained enough respect for human life and dignity to be saddened and horrified by violence and death, as opposed to the cynical disrespect and gallows humor that modern police officers in our world treat suffering and cruelty with, if only out of ugly necessity.
John Spartan made Huxley a sweater as an apology, how cute!
Spartan getting reacquainted with Zachary Lamb, who had been a young recruit before he was frozen and is now an old man, one of the few people who remembered and believed in him.
When Spartan finds out that the delicious hamburger he was eating was literally made of rats, he remembers the poverty and hardship that the poor cook and her fellow underdwellers have to endure, and having actually enjoyed it, sincerely tells her that it's the best burger he's had in years, which she joyfully appreciates.
In a small moment of mutual bonding, during their final battle Spartan repeats the Pre-Ass-Kicking One-Liner "Is it cold in here, or is it just me?", to which Phoenix mutters "Good memory". These men may be mortal enemies, but they obviously agree this future world they've been tossed into stinks compared to the past.
