Correction, is good for growth. And when you correct or fix the wrongs in your life - a good example is set for people to follow. People are watching you if you are right or wrong. If you ignore correction, you will lead a life of destruction, and worse than that, you will lead other people in the same destructive path you are going.
In other words,
Improvement is better, but ignorance leads to death.
Thanks for the question.
