If you're curious about the whole trial, here's what happened:
(Warning: Super long. )

Nephthys was brought in by Horus to testify regarding Set's rule. She confessed that the reason why Set became mad was because she had an affair with Osiris and that she loved him(which I think is a lie and she was just saying that to lessen Set's punishment).

(Speculation here: Isis fainted because she did not anticipate Nephthys to come and for Anubis's curse to reveal in front of everyone - rendering her unable to control the situation)

Nephthys also said that Set never imprisoned her and that she imprisoned herself and Set had always left the prison doors open, so she could leave whenever.
So Nephthys starts crying and states that it's all her fault, trying to convince the Ennead that she's the reason to Set's madness and that Set's punishment be lessened.

This is where Ra (the baddass, the legend) brings down her whole argument. Ra states that they're GODS. They are not bound by human traditions. Something as menial as cheating shouldn't bring all this chaos. (which Thoth retaliates with "Things have changed, Ra." but got a staredown (lol) ) Ra also questions why she's only asking for Set's forgiveness when Isis is also an involved party. Shouldn't she be begging for Isis's forgiveness as well?
And once again, Ra inquires about the night of Osiris's murder and suggests Set's heart be put on the scale.
This triggers Set and he starts laughing in madness. He screams to them to basically just kill him and he breaks out of his chains.

This is where Isis's dillemma comes in. On one hand she wants revenge against Set for making her miserable all those hundreds of years..On the other hand, she also knows Set is as much of a victim of Osiris as she is. Seeing Set miserable like this, she does pity him.

Then Horus (the best boi that he is) "subjugates" Set by faking to knock him out so Set doesn't have to speak about his experience.

Isis debates on whether to speak about what happened that night now that Set's "out of commission". Osiris's honor will be stained and Set's rape will be revealed (which is obvious to her that Set DOESNT want to reveal -even stating he'd rather die)

Isis proposes to Maat to destroy Set's soul. (It's her revenge against Osiris is to destroy Set's soul so he can never claim him in Duat.)
Ra argues against it and says it'll be a waste to kill her "cute great-grandson" and proposes to Maat that it would be more beneficial if Set boards the Sun boat with her.
Nephthys also argues against that and brings up the lost souls Set has slaughtered. She pleads his punishment just be him collecting the souls he cut.

Set cuts the facade and stands up. He states that he's ready to take any punishment they have for him.

Maat delivers the final verdict:

"Set, this is all the sins you have committed.
Your sins, accumulated for hundreds of years, are so deep and heavy not even this papyrus can contain all of them.
Among them, the sin of disturbing the order of life and crushing numerous souls is a felony that shakes the foundations of Egypt.
However, if there is still a way to save those poor souls, this cannot be overlooked. This chance that I will give you is not for you, but for those souls.

I hereby decree!
Set, God of War and Dessert.
All of your achievements and praises be cleared.
Set's temples, priests, and sacrifices will be disposed of by the God of Magic, Isis.

The evil Set has committed countless sins and will be bound by this sentence.

You will have a probation period before your sentence is executed.
Collect the souls you have crushed during this grace period.
Let them do their best to release their curse and correct the order of life.
If by any chance you harm another human soul, this probation will end.
If you succeed in assisting all the souls and restore the cycle of death, you shall board the Great Sun Boat and row for all eternity.

If the souls are not collected and the cycle is not restored, the demon Set, shall be destroyed forever.

You will not have the power of Godhood to assist you.
Only through atonement will you receive the answer of the sand.

As a Demi-God, not the God of War and Dessert.
Look up at the world from the lowest, look back on your sins and repent.

This is the ENNEAD.
This is our verdict."

Maat proceeds to confiscate Set's godhood powers and ends with:

"Through this,
the ENNEAD trial is dismissed."
