[Spoiler media] Theory - Possible parallelism of Petra Leyte (Arc 9) & ■■■■ (Arc 6)

With the recent revelations of arc 9 and Petra with Subaru's book, I thought about the possible parallels of arc 6-9.

Unlike “Subaru”, Petra does not forgive bad people (Foreshadowed at the beginning of arc 9).

Like “Subaru”, Petra will live what Subaru lived. Maybe all the books if Petra becomes obsessed with obtaining all of Subaru's knowledge (Direct parallel to “Subaru IF Gluttony”).

Unlike “Subaru”, Petra will not forgive anyone if they killed Subaru. Including Garfiel and Meili… the people who ARE with her in the tower.

Unlike “Subaru”, Petra is a child who will have an adult voice in her head (Subaru) trying to stop Petra from falling into the temptation of murder. While “Subaru” is an adult who had a child’s voice in his head (Meili) tempting him to commit murder.

In arc 6, we had “Murder became a habit”; in which “Subaru” did not intentionally kill anyone after having a turning point. In arc 9, there is the possibility of “Murder does not become a habit”; in which Petra does kill someone (probably Milei as a parallel to Meili being killed in arc 6 by “Subaru”) after having a different turning point than Subaru.

That is my theory on possible parallels between Subaru and Petra for arc 9, what do you think of this theory? Also, I am sorry for the translation issues. English is not my first language.
