Anger Good or Bad

 People treat anger in different ways as per their own perspective but my intimation and intellect is saying that anger is just like a fuel which can elevate you toward the highest objective of your life. It also depicts thy inner ability to be having warmth in thy deep down and exhibited thy true nature. For instance imagine if you are walking on the railway track and the train is running in its full speed, but suddenly your mother sees that. What would be her reaction?  Is it possible that she will keep remaining calm and quiet in spite of knowing the fact that you are playing with fire? Rather it would be almost impossible for your mother to be at the calm state of mind. Out of love she will turn to be quite aggressive and in a fit of anger she will jump on a track, put you out and give you a huge slap. 

Now tell me anger is good or bad! 

      Now lets take one more example.  Suppose someone is ready to hurt you and you have now observed his intentions. Would you be keep remain calm and quiet and allow him to kill you? Perhaps not rather out of anger you will attack him with full of your force.  Now lets take one example from Mahabharata.  When Sheshupal was abusing Sri Krishna unnecessarily, but due to the generosity of Krishna He never reacted because Shishupal was younger to him.  Therefore, he said that He would pardon him for his hundred mistakes but when he exceeded his limit then he must be ready for the consequences.  Just like His promise He gave him hundred of chances to correct his behaviour, but when it was depicted that he wasn't learning from his previous mistakes and blunders and keep on insulting Krishna then Krishna beheaded him with his sudharshana as a last option. Though Krishna didn't want to kill but out of the fit of anger he killed Shishupal.  Now my question is:

-Why did Krishna do so?

       Perhaps the answer would be that he knew if he would not kill him then his dignity might be polluted in front of others which Krishna don't want to be. But it should not be taken wrongly by the reader that killing is good and whosoever tend to insult us; we must kill that person because perhaps then there will be a complete chaos everywhere.  Rather we must be ready for the self defense not only physically but mentally also. Thus your Anger defines you and who you are because your anger exhibited your true personality.
