This is an interesting South Park cartoon video; lame and sarcastic but actually meaningful.
In life, you may meet some crooks and wish to redress justice over minor matters. You can maintain your principles and spend all your time to solve the problems but you gain nothing after all. A hero is never named or recognised for a minor act unless you have the luck. Often you can only face setbacks in the end.
I used to brood over hypocrites in IRC and then the hectic and unfair life in army; I could not seem to help but instead, brought my life to a greater grieve.
