How does one turn out the way they do?

The old town drunk died. His two sons, the bank president and the new town drunk were at his funeral. An onlooker, surprised at how different the two sons were, asked each one how he turned out the way he did. 

The bank president responded, “With a father like that, how else could I turn out?” 

The new town drunk responded, “With a father like that, how else could I turn out?” 

For what it’s worth, I am like the bank president. I have no idea why. All I know is that no matter whatever anyone ever did to me, it didn’t matter. I have no idea if someone who turned out like the new town drunk can change (although I imagine it happens all the time). All I do know is that “it is possible” for a victim to succeed and overcome all of his “darkness”.
