Why do you think Nate chose not to press charges on his dad?

I think that it's hard for any kid to be in that position with one of their parents. Even if one of your parents did something really bad you still love them because they raised you. I think that this is the position that Nate is in. He doesn't particularly like his dad too much but he's not able to press charges on him. If the conditions were different Nate would probably be able to. Such as if he didn't know his dad and they had just met. Then Nate wouldn't have many attachments to him and if he was mean Nate wouldn't love him.
