The funny thing about Zero Hour is how clear the Sinestro influence was behind the scenes which makes sense to me (what a great retcon by Geoff). All those cosmic shenanigans scream Sinestro to me: perfect order through absolute control.
Sinestro clearly knows Hal's need to protect, and warped that to the absolute extreme. What a brilliant revenge.
Still, the true hero was always bubbling underneath all that corruption. I love this page; Geoff was firing on all cylinders back then.
The soul of Hal Jordan was in a tug of war between two god-like entities, yet he was still going around looking after his folks.
