Whats so wrong with wanting life?  Why instead of help do we have to fight?  Why must we kill instead of save?  What in our life causes us to never end the killing, the murders, the everything sad?  Is it honorable to take an others life to save someone else?  Are we all not on the same planet with the same goals, goals of happiness and peace, goals of our family being safe and our God being honored?  Whose right is it to say who dies and who lives?  What makes God unable to do so?  Why cant we save without death?
