The people around you take notice when you set a good example. The world could be made a much better place if enough people set a good example.

Show the people around you that it's okay to make mistakes as long as you do your best to make up for them. Pleading temporary insanity keeps mass murderers from the death penalty.
Parents blame heavy metal music for their child committing heinous acts.
Others think hand guns should be outlawed because most people can't use them responsibly. It's not like we can take a measurement of responsibility, or graph it out on a chart. Responsibility is too subjective. The truth is that responsibility is based on individual experience and everyone's differing priorities and values. This is the problem that we face.
