The Wrath is there to test it's willpower against that of the host. Corrigan was never really able to control the Wrath well. Neither was Zauriel, when The Wrath entered his body in issue 3 volume 4. Without a host, the Wrath is in full control and just destroys, as seen in other comics as well, and I gave the issues for those already. As well it talks to the host. Even fights them sometimes, as what Corrigan did in issue 36 of volume 3.. The Wrath told Hal he could never have the full power of Spectre because it didn't trust him, also comics I gave the number for.The Logoz is power it kept when Hal outwilled the The Wrath's need to even exist for a great period of time. And so Hal earned the Logoz. Hal in that first arc and in the Legends of the DCU 33-36 that proceeded it, keeps mentioning of testing his willpower against The WRath, but is wollowing in the self doubt of what he did as Parallax. And the Wrath controlled him, just as it did Corrigan.
The Logoz itself told Hal it was finally free of The Wrath's tyranny, controlling it's power. Hal is the only person to have the willpower to defeat The Wrath in such a way. The ONLY one. And behind that, he found The Logoz, and thus, started guiding reality as a whole before the end of the series where he learned the full scope of his mission and powers.
The on panel evidence, is the picture I'm painting. I'm giving the quotes, issues, pages. And then even the times its supported in previous comics, and even in the whole previous volume, as well as afterwards. This is not a theory. Just what is told and shown on panel.. anything else is speculation.
I've feel I've probably even proved that you don't even own the issue in question as you're denying what is written on them, when the Logoz in one bubble says "Call me a thought in the creators mind" and then on the next panel identifies itself as the Logoz. lol.
The truth is, I own these comics in question, and they support their own evidence.
