Ethics isn't black and white, it's more often gray. If you are a "servant of the people" do you have good intentions when you go to fire a subordinate who isn't cutting it? Or are your intentions "bad" as toward that one employee who you are throwing out of work? Is he not one of the "people", too? And what of your intentions when you change your mind in the middle of the termination interview because you are touched by his plight as a single father of a 10 year-old girl, as you are the single mother of a 10 year-old boy? Have you been corrupted? How about when the subordinate's sob story is almost all lies, not a single parent, not struggling to make ends meet on a government salary, has been siphoning money off the state for years? Where does trust go as a management tool when you have been hoodwinked as Olya was in that last?
Trust is built grain by grain of white sand over time. Corruption of a basically good person begins, rather than with a sudden, blinding sand storm, with grains eroding off trust with time, grain by grain, white grain by gray grain by black grain until a basically good person can no longer distinguish white from gray from black.
