Should we eliminate fear?

Fear is the body's way of protecting itself.
Instead of trying to eliminate fear, we should try to understand the object of fear. We should see if our fear is reasonable.
Is it merely an imagined object or an actual object ?
If it is an imagined object, can it become an actual object ?
If it is an actual object, is the object dangerous ?
If the object is not dangerous, we can ignore it or act upon it.
If the object is dangerous, we can fight with it or run from it.
