Accountability - officially extinct?

Why has accountability become an extinct concept? Why is it so difficult to say “This is mine. I take responsibility for it.” Heaven forbid something should fail. Heaven forbid someone should say “You should have done this better.” Are we really that afraid of such consequences? Are you really going to be executed for a mistake? Who on this earth doesn’t make mistakes? Doesn’t it seem logical that you can’t learn anything if you don’t take responsibility for the errors in your life. A brutally honest evaluation of how you contributed to a situation for better or for worse will tell you how you can improve as a person. Those people who find it impossible to actually make a decision and then take responsibility for it are people who are incapable of growth and improvement. What’s the point of this life if not to learn and grow?
