Not quite. Teregard was completely under his control and still worships him to this day...which explains why it's so orderly and cold over there. We were told shortly after TWW and Guthixian memories that Saradomin abandoned the humans because they were too weak. Runescape doesn't need a hero...it needs a villain. An all encompassing force of evil that will remain ever-threatening and use chaos to make the peoples of Gielinor tolerate each other, grow strong together, and fight side by side against this evil. I am that villain.
