Abuse of ethics

[Rodion Romanovich]

What are your most often encountered examples of abuse of ethics in your everyday life? Here are a few quite annoying ones I run across quite often:

- a person wants something from you, but that person has never given you anything back and probably never will. So when he wants something, you demand something in return, that would be easy for him to get hold of and give you. But when you do this, he replies that it's "unethical and calculating" to demand something in return, attempting to abuse ethics to be able to get everything he wants from you, without giving anything at all in return.
* Solution: generally, I say "no deal", and the problem is solved

- a person does some unprovoked evil to you, then insists that "revenge is unethical" when he sees your ability of reprisals. It is obvious from repeated unprovoked attacks that the attacks are deliberate and not merely an accident or coincidence. The person uses ethics as a way to protect himself from any reprisals while unjustly trying to steal what he wants.
* Solution: since it's deliberate beyond doubt, I make clear that in my ethics system, "turn the other cheek" doesn't apply to deliberate attacks, but only to accidents, and that in accident cases the offender is expected to repair the damages, and in deliberate repeated attacks, the offender is expected to pay indemnities of a size that is precisely so large that 1. damages are repaired AND 2. the total affair results in no gain for the offender.

So, what are your examples of people abusing ethics in your everyday life? And how do you generally solve these problems?
