Do it takes a realistic analyze over children to be a good parent?

When I watched movie name Rambo last blood. Made me realize any parents have to be realistic with what children will do.

Like assuming children will listen and do thing what parent tell them to do.

In this movie, they told this niece to not bother searching for her own father also do not let friend helping her finding her father.

She just do it anyway which how she got herself killed.

So I'm thinking can't John Rambo be more reasonable maybe go with her to let her see her father without friend which a bad kind of friend because friend sold her out to sex slave in Mexico.

Lastly John Rambo made move too quick against gangster without investigating to locate her to to save her without dealing with gangster.
