The significance of doing good lies in doing good itself, and in letting those who are desperate, have no good deeds and have no warmth get good deeds and warmth.
Good deeds do not ask for anything in return. As for some bad people who don't expect anything in return, they receive good deeds-I have to confess, this is normal. This is a common fault of human nature. Most people will not feed back those who do good deeds, and very few people will bite back. Of course, there are very few people who repay kindness!
Goodness is a voluntary contribution that transcends feedback, spreads human ideals, promotes human progress and serves the whole society. It is by no means commercial futures, nor is it pragmatic.
