If we can solve the problem by being brave, of course, we should be brave first, because it saves time and can stop the danger in time.
On the other hand, when it is possible to endanger one's life in order to be brave, it is best to call the police first and then consider the question of wisdom. Other people's lives are precious, so is their own.
There is another situation that needs to be guarded by life. Then, we will bite the bullet and not let our loved ones get hurt, otherwise, we will have a bad conscience all our lives!
