How long will it take me to learn that Dipper sparing Blendin Blandin from death in "Blendin's Game" does NOT make him a douchebag, even though Blendin wanted the twins dead?

In "Blendin's Game", Blendin invokes Globnar on the Pines twins, Dipper and Mabel. If he wins, then the twins are no more. It seems as if they are going to lose, Blendin gets distracted and the twins win. They get to decide Blendin's fate. Mabel shouts for Blendin's death, but Dipper scolds the sister. Dipper allows Blendin to live, as long as he is monitored by TPAES.
