Personally I hated advanced warfare mostly because I felt you shouldn ' t have fought against Irons . You were best friends with his son . He died doing his duty and you feel guilty because you couldn ' t save him . Irons gives you a new life and a new purpose . Everywhere Atlas goes they bring peace and prosperity . The KVA were unstoppable and only Atlas was able to stop them . Although Irons let them carry out their plans in order to gain influence he did it for a long term goal . His goal was world peace . He was brutal but extremely effective . I think he would have achieved his goal if it wasn ' t for Mitchell . He would have created a unified world where war and differences won ' t exist to stop the advancement of humanity .
