* This is purely my own OPINION * I think there’s more to the story of Prince shooting Cayde then just wanting to kill him. I think Cayde’s previous devious actions maybe at play here. You remember during Osiris DLC Cayde was caught up on the Vex warp flaux. What if Cayde unknowingly contracted some sort of robotic disease that would be detrimental to the rest of the universe. And Prince is just portraying the antagonist to get the Vanguard involved in a weird twisted way to save Cayde and rest of Destiny Galaxy. Well this might be far fetched but Cayde being carried away by the Prince has some major implications, why would he need Cayde’s body, just ponder that. Cayde is too major and most popular NPC in Destiny for Bungie to just kill off, unless they are planning to replace him with “The Stranger” Exo then I see no benefit of them losing their most popular character
