You: No they don't. Love can be in vain but still keep one from wanting death and desire to help others can continue even when it is obvious that you can do nothing significant.

Aaron: There is hope everywhere in those things. Hope that an unrequited love will be returned is what keeps a depressed lover from killing himself, and hope that you will be able to make a difference to someone, even in an impossible situation, leads people to help others.

You: What you are saying is true, but these types of hope have nothing to do with a hope for justice and therefore do not imply that it exists. They can exist even when an individual believes that there is no justice either in this world or in the next.

Aaron: This discussion has turned into an argument about personal definitions of certain words and can clearly progress no further. I think it is time to change the subject.
