Yes, it is really a need to help someone in case of danger situations. For example, that person in trouble is your best friend which the situation is a bully. The bullies might do physical or a mental abuse to her. Now, your bestie sees you and calls you for help. Which would you rather do? Help your friend out of trouble and facing the danger face to face? Or you just walk away and make it look like it never happened? I would rather go and help my friend get out of trouble, cause it is not only that she is my friend, its a person i really care about. When you don't face danger a feeling of guilt always runs up your spine, feeling regret for not helping a friend in need.
