Both Hunters and Warlocks have similar goals. They are both in pursuit of knowledge and discovery. They just have radical different ways of going about it. Neither has the greatest respect for the methods of the other. Lab research vs field work, teamwork vs solitary, etc.... Titans main goal is to endure the survival of man/exo/awoken kind on the field of battle and to protect the innocent at all cost. Mind you, Hunters and Warlock (in general) only tease each other about these things.
