I would, say don't be so quick to trust the warminds. I know this is a different universe and all so this is complete speculation on my part. Every Bungie game that had AI in it also had the common theme of them struggling with going rampant at some point. Cortana and Durendal being two that come to mind. Since the Rasputin has been dormant and cut off for so long, who knows what kind of "mental" state he will be in. Be wary fellow guardians! An unshackled AI can be unpredictable.
