I don't remember saying that. I strongly dislike the Spectre as a character, and would only write him in a setting he was canonically part of. And even then, only if there was no way to avoid it.
There is this character called Raguel in the 2018 issues of the Lucifer comics that basically serves the same functions as the Spectre, that being God's wrath and vengeance.
He's powerful, but not as bullshit powerful as the Spectre, so if that's your hang up with the Spectre, Raguel may be a better alternative.
It's more 'his alter-ego was a supervillain and he's building an army of supervillains and has the same weapon'.
I think he told them that he worked with the League in his universe.
Though I guess they either didn't believe him, or thought the versions on his universe were also criminals
Exactly, that is what makes the best episodes of "Law and Order". You can see both perspectives of the case and each side has a 'moral' argument, but Peter has a stronger Legal argument.
I also kinda want to see Paragon Paul go to Earth-12 to testify in the case. Just to give a good dressing down to the Guardians and the Justice League. Maybe have the Guardians bring an Honor Guard team who gets spanked like those rookies on Oa-16 when there was that "misunderstanding" about Paul being invited there.
Then end things with Paul making Peter a Lantern. That would cause quite a bit of Chaotic Good. All Hail Eris!
The look on the Guardians and Greenies faces would be priceless.
The Guardians may only give a bit more shit if paragon wanted to talk to them, instead of some mortal, but they still may not care, since they still don't care what he has to say, and Paul may not go to war with them for just one guy.
If Paul fights a Honor Guard then he might receive a difficult fight.
The Lanterns he beat on Oa were rookies, and a lot of his fights with other Lanterns were spars rather than actual fights.
He may bear them, but it may not be easy.
Peter may also not want an orange ring if he fears going insane.
