Where did I change the parameters? I compare a kind man -- one who gives his excess to others -- to a greedy man -- who keeps his excess to himself. You evade the question by imputing greed into the first one, then pretend that I insulted you.
Let me make sure you understand the question. The man has an excess of $100. Some other has a need of $100. If the man acts kindly, both he and the other one have their needs met. If the man acts selfishly, only his needs are met. Do you maintain the ethical equivalence of the two behaviors, and if so, on what rational basis?
I evaded no question by imputing greed, and your whole flat earth description was an insult that had no necessary legitimate purpose with regard to anything said, other than to purely insult.
As I see it, kindness in a general sense may or may not be a good. When viewing it as a good (which I usually do), it is only a good ethically speaking, where it is not required by expectation or law. The instant it is granted a higher ethical standing, it then become required by expectation and thereby looses part, if not all of the ethical aspects of its good and thereby begins to fall into an unethical category.
In this regard, kindness is an opposite of lets say honesty, where an increased expectation and duty, takes nothing from its ethical standing.
