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. People understand that there's no concrete definition of responsibility, and they try to take advantage of its flexibility in order to avoid paying for their own actions. You know people like this. They act recklessly and blame it on someone or something else.
