Ryan,

Human beings are born with the right to commit mistakes learn from them and improving themselves.

Going a step further we can say that human beings alone have the capacity to qualitatively change their thoughts beliefs and culture.

In the insatiable quest to find the answer human beings question the knowledge gained . Instead of just feeling regret he should look at the improved way of looking at things that he has learnt.

As he grows and matures he will always evaluate and understand the futility of the earlier actions performed. This is a normal course of learning every person will take.

Instead of regret measuring the path travelled would be a better way to look at his past.

Look forward to read more from you

Best,
