At some point, you have to stop running and turn around and face whoever wants you dead.The hard thing is finding the courage to do it.

This phrase is suggesting that, even though it might be difficult, it is important to not run away from a situation in which someone is trying to harm you. Instead of running away, you must face the person who wants to harm you, even if it takes a lot of courage. This means that you must be brave, and unfortunately, it might require some difficult decisions.
