No role models for me.
In my opinion, the only ones that could possibly ever be role models to young children should be parents or perhaps older brothers and sisters. Then again, those parents need to teach the child that it is to make its own choices and go its own way and not to become exactly as their parents.
"Tabula rasa" in Latin, is basically the keyphrase of existentialism. You begin as a blank individual, you'll have to fill in yourself along the way.
Now, I don't think it's absolutely blank and only filled in by you. Of course there are always certain influences from outside that affect you. Some of which you can control, some of which you can't. However, it's up to you to decide for how much you let those influences affect you. In the end you're responsible for your own actions and when something goes wrong you'll have to look at yourself first.
And then we come to a common problem of modern day western society: the role models. Everytime something goes wrong people immediately start pointing their finger at others. Many parents are the worst in this, probably. When something happens to their children it's always the fault of MTV, violent games etc. Hardly anyone says to themselves "well let's see what I could've done to prevent this and see what I can do to prevent it in the future." The message is: take your own responsibility and do it as much as you're able to.
