I just thought of something and apologies if it's already been discussed but if after he started talking in orange quotation marks Paul knew everything he wanted and why and after talking in yellow quotation marks Siskin presumably had the same for fear then what does that mean for Guy?
My theory based on what we've seen:
Guy knows that Guy is Guy at all times. He also has perfect awareness of the fact that he is Guy, and of what he has decided to do.
I
think that, in the sense that 'Avarice' can be roughly seen as 'Desire/Greed/Want/Personal 'should be' ', 'Will' can be roughly seen as 'The conviction/determination/certainty with which decisions are carried out'.
Based on the reactions of Paul to the Medusa Mask, it probably also gives him the ability to mostly no-sell emotional effects which do not come from within - if someone tries to fill him with rage not stemming from himself, then Guy can just go, "Uh, no, I'm Guy and Guy doesn't feel angry about that."
So many points, here...
From Wonder Woman:
She seems reluctant to face the fact that he HAD a team - just not the Justice League. It must really hurt to suddenly see just how much of his trust she had lost.
That's EXACTLY the sort of thing that "SI" needed to know about! He could've been part of the planning! He couldn't ask any League-members about possible plans without risking a leak that could get back to Nabu & get his guard up...
...& while we're at it, just HOW did the League-members manage to keep their plans out of Nabu's awareness...???
From Hawkman:
...& from Superman:
- You knew the League's plans for Nabu, Hawkman. If you knew as little about these plans as "SI" did, would it still look like an 'overreaction' to you?
- The League kept their OWN side of this equally secret for the SAME 8 months, Superman. & if "SI" felt 'justified', then why bother volunteering these answers? UNLIKE a supervillain, "SI" is freely submitting himself to the judgement of his peers.
What they both overlook is that "SI" is freely reporting his actions, just as fast as his hospital-recovery allowed. This is NOT self-justification, this is CONFESSION, presented when his actions can no longer be blocked by them. There's no attempt to lie, evade, or hide from consequences. There's no blackmail here. If arrested, he'll not fight to avoid arrest - instead he's told them, IN ADVANCE, what his courtroom defense will be. Win-or-lose, he's accepting the consequences of his choices. Everything he's done since he awoke in the hospital has been part of cleaning-up the messy loose ends left in the wake of this operation, including this de-briefing before the League.
Not official canon, yet. (But here's hoping!)
Also, to respond more specifically to some of your points:
Yeah, Wonder Woman maaaaaybe doesn't want to face this right now.
The League never actually advanced a very serious plan. They didn't so much hide their plans from Nabu as... when Nabu said, "No" and left they accepted that. More importantly, the possibility of a telepath detecting their plans wasn't a problem, because they didn't feel betrayed by J'onn J'onnz, and Nabu may not have been otherwise checking for such plans
or may have accepted that their plan was basically to do nothing until they could present a full solution that required no effort on his part.
Yeah, Superman, Wonder Woman, et al are kind of forgetting that the reason Paul hid this from them was operational security and... because he saw them lying, badly, to make sure that a slaver could keep his slave.
How Paul presents his "I will testify honestly" is definitely blackmail-flavored, even if it's not blackmail. He's saying that, if he is arrested, he will testify honestly and completely, without regard to protecting them - but because he has eight months of built up betrayal-anger-pain-scorn-hate, he's choosing a confrontational path.
This is... the purpose of revenge, in a sense. Someday the League may look back on this and realize, the Lords of Order may look back on this and realize... This is karma. When they released evil into the world, when they hurt others - the world responded, others responded. Harm others, deceive others, and you will ask others to harm you, ask others to deceive you.
There is a reason that when I referred to the 'base urges' and 'grand ideals' that the Guardians would excise, I associated Rage and Justice, and Greed and Beauty. Perspective matters, context matters.
