Yeah I also get mad at this sometimes, but I always try to remind myself that even if a bad, influential person dies, another bad person takes their thrown by every dirty trick imaginable. This problem must be fixed from it's roots, which is to be a good person and raise children who grow to be good and honorable people. Everyday not only think about yourself but also about others beyond your family and friends. Help anyone your hand reaches to and always prefer other's benefit from yourself. I know not everyone can be like this but even if 60% of people where, the world would have been a much better place.
