Existentialism
Existentialism, a passing ideology that had its best time back in the 19th century, says that finding meaning in freedom requires individuals to continue to construe their essence in response to the conditions of their existence and thus is responsible for his actions.
People make countless choices in a lifetime, each person makes them every day, and these choices are that person’s choice and only that person’s choice to make. The reasoning behind this is that every single time we make a decision about ourselves, we are expressing what we consider to be the morally right thing to do in that specific situation.
