Whether or not the Vanguard condones it (the grimoire doesn't specify) guardians have used torture (at least one example in the grimoire, where a hive wizard is tortured by a warlock for info on Crota). #LoreCorrectionCorrected

Which warlock?

Ghost fragmenr warlock 2 My name is Eriana-3, disciple of the Praxic Warlocks, marked by the Cormorant Seal. We came here under one banner, united in a host of thousands, to claim the Moon. But the battle goes against us. I have taken a prisoner and this is the record of its interrogation. If I transgress in your eyes I ask for your forgiveness. [sound of current or discharge] /Eriana. It responds to pain. It responds to the Light. Hurt it again. Monster, heed me. Who is your master with the sword? [static event] I can hear it. In my head. The swordbearer’s name is CROTA. Record that. /Should I burn it again? No. I think you’re only feeding it. I will touch its mind. Ghost - help. They call you Wizard. You must be ancient. I think you value power very much. Will you still be powerful without this piece of your mind? Tell me how to kill Crota. [static event] It showed me the battle. It showed me Wei Ning dead on Crota’s blade. It showed me how Crota killed a Guardian with a screaming knife hammered out of his own Ghost. So I will take a piece of its mind, and ask again. Tell me how to kill Crota. [static event] Incredible. Where? Where is his throne? Where is the twilight world under the dead star eye? /Eriana there’s word from the company in Mare Imbrium. Crota is upon them. Half a hundred dead. They need us. Tell me where! Tell me how! TELL ME! [static event] /Eriana what did it say - It showed me how it did this, just exactly this, to an Awoken man, the knives arranged by its will, like little silver ships, like Ghosts - It laughed at me. It said we were the same. /Crota marches with a thousand Knights and they say the sky above Mare Imbrium has turned into green fire. They are dying in numbers I cannot bear to repeat. He kills them one by one with a sword that eats their Light. Eriana, we have to do something - Kill the Wizard. Scatter the ash. It has nothing but lies to offer. Get your Sparrows. We have Light and fury. That will be enough

The interrogation was done under circumstances where it was needed. They didn't have the power or resources to find out, and she acted under her own need for revenge and for information.

1) torture is still torture whether you claim necessity or not 2) extenuating circumstances have been claimed by almost everyone defending torture in the last 50 to 100 years 3) its a terribly excuse anyway because studies show torture is ineffective because it generates unreliable info

We still haven't killed the kell of kings. SOMEONE has to know where he is.

They don't have a kell from what I know

Yeah. We need to torture Randal the Vandal.

The question is, [i]CAN[/i] we torture Randal the Vandal? Or is he so badass, that he would torture us?

We can't torture him. Probably why the fallen have given him all of the information

Randal is the real Ultimate Boss in Destiny. I bet he controls everything AND causes all the game lag!

Yeah, and the last boss we have to face is Randal, but we have to face all of the other bosses in succession with exposure. He then reveals that he is the ultimate boss.

And we are stuck using strictly nerf'ed weapons & abilities!

What if Bungie does incorporate Randal? But he is a hidden boss who disappears from planet to planet when his health reaches a certain point

He knows everything.

He'd be a boss like the UR- dragon was from Dragon's Dogma, where it takes the whole community to kill him but the person who gets the last blow gets the exclusive "Randal armor set" haha
