Why?

If love hurts then why do we seek it?
If we break promises then why do we promise in the first place?
If hate is bad why do we carry it within ourselves?
If change is good why do we cling to the past?
If revenge is pointless why do we seek to carry it out?
If life is unfair why do we seek to change it?
If humans are smart then why do we fight?
If people die then why do we seek friends?
If what goes around comes around why do some people never get their retribution?
If people fight why do we seek peace?
When all is lost why do we so desperately cling to hope?
If we care why do we ignore the people that need us most?
If life is precious then why do people kill?
If love is always there why do some never feel it?
