This philosophical debate about good, evil and care of the elderly had a notable flaw, the omission of neutrality as an alternative.
Call it yin/yang, light/dark, good/evil, left/right... or even beer/lager if you so desire, the balancing, understanding and harnessing of both 'dark' and 'light' creates strength, enlightenment and true freedom. It is very easy to be evil or good, you have a set of rules which dictate your actions. As a neutral you have to think for yourself.
