What is the definition of a friend?

Russell: What is friendship? Marcus: A friend is one who can help you in times of need. Russell: But what if the person is after something that you have? Marcus: Then I think he is not a friend. Russell: Then how would you define a friend? Marcus: A friend is one who can help you in times of need, but not for any gain. Russell: Then maybe he hates you, and helps only because he …

…with the intention of harming you. He must also not lead you astray or forcefully make you do something against your will. A friend must also have true friendship with you and be your friend because of friendship. If he makes a mistake and harms you can forgive him? Marcus: Yes that is right. Russell: I think that is a very good definition and I cannot find an exception. So we shall end this discussion.
