It reminds me of some points I used to discuss. Is this principle very basic and just good enough to start with, but it alone cannot determine what is right and what is wrong?
I think that what is right and what is wrong is relative and depends on the choices available. For example if there are 2 choices amongst many others then if the choice A was relatively better than the choice B then B automatically becomes wrong even if some scripture says or some society says that both A and B are right choices.
From the above: Thus, sometimes not doing anything also becomes wrong when doing something would have been better. Even though doing nothing wouldnt have harmed anyone.
