Handbook of Epictetus: FIRE! (26-30)

Epictetus said: "Just as target is not set up to be missed, in the same way nothing bad by nature happens in the world" (Epcitetus 10), and I agree.
Whenever someone is bad, he or she is bad by mistake. We might say that if a child is born into a hateful family then the child was born to be bad as well, but also, if we fire a shot terribly, then we are bound to miss the target. I think Epictetus used a great example to communicate and summarize his theory of good and bad people.
When baby is born, it depends on the adults in charge of him to take care of him and teach him the ways of life, in other words, everyone's shot was fired by whoever was in charge of us when we were learning and it is very difficult to change the fate of the missile once it is in mid air. At the same time, if the missile is deviated, it is hard for it to shoot another missile in the right direction just the same.

How can we be good or bad if we don't know the difference between either?
