Man does not act, generally it responses. Man acts in response to some object, person or situation, sometimes in a good manner and sometimes in a bad manner. The farther the cause of a good deed is from us, the higher is the level of that deed. The farther the cause is, the more it comes into the category of charity. As much it gives  happiness to someone in front, more than that it gives peace and satisfaction to us. This is the path of public welfare. 
But at times we see someone else misusing his power, then by preventing him from doing so, we prove an act of charity. But such type of charity should be done very carefully. Because regretting after that will not be fruitful in any way. You just cannot help when the bird pecked the field.The arrow fired from the bow never comes back.
Sometimes, it also happens that we do injustice to someone for the sake of someone else. So I want to give message through this video/editorial that when we do injustice to someone  for the sake of someone else, It should be thought long before that who will bear the consequences, for whom we are doing Injustice that person will suffer or being a doer we will suffer ourselves. We should also take into consideration that whether the person we see as victim or in a pathetic condition, is he really deserving pity. Everything should be understood very well, given a second thought because always, the doer of the karma has to suffer the consequences of that action, whether he has done it knowingly or unknowingly, intentionally or unintentionally. did it for self or for someone else, did it at it's own discretion or under the guidance of someone else, did it happily or out of compulsion, did it in haste or with patience, did it in this life or in past life.
Sometimes people cunningly present themselves in a pathetic form to fulfill their selfishness, and we tend to believe it. It is also worth remembering that it is not always true even if seen with eyes or heard by ears. Any object, situation or event has different consequences in different circumstances. Again, no object, situation or event is alone in itself, there are many different factors working behind it, there may be a chain of deeds behind it which affects its appearance. And those influencing factors hidden behind it are not visible or heard to us. Also should not forget that God is running this world, not we.
The above statement does not at all mean that we should not extend a helping hand to someone after seeing him in painful condition. We must help because this is the proof of humanity. It is for us to brood over the matter, then take a decision and then act accordingly. It would be more preferable to act intelligently rather than emotionally. Just as death is certain by drowning in water, the same way salvation is certain by drowning in devotion. In the same way, after doing work, it is also certain to pay for its fruits. But don't be egoistic in times of happiness and don't lose faith in God after getting sad results. 
Sometimes, even after doing a good deed, a person remains restless because he tries to review that work from different angles, different points of view, so the clouds of apprehensions start gathering. The nature of human mind is like this. That is why any work should be done only after deep contemplation. The truth has been said by someone, "Without thinking if you act, you repent." Your right actions are your destination and if you ask others the way to your destination, you will go astray because no one else can know the importance of your destination as much as you can know.Therefore brood over the matter and then perform any action, then also without any hurry. So that, at the end it can make you smile.
You know that  smile is not only good for health but also is the greatest medicine that effects not only you but also others around you. So find chances to smile. Otherwise also, smiles are fat free, sugar free, reduces BP, helps relieve pain and depression, require no batteries absolutely free of cost--------so keep smiling.
