>>99556206>Suddenly>Bloodthirsty villainA), the whole Fallen Hal thing was built up over the course of a few years. Hal was getting older and generally was a sclubby, jobless wreck while Guy was GL. Coast City was blown up during Death/Return of Superman and Hal felt powerless to stop it. Repeated attempts to rebuild it or to attempt to time travel and stop it were prevented by the Guardians, in addition to the stresses that Hal endured in losing his friends over the years. Barry, Clark, his fellow GLs, so on.
Hal was basically a walking timebomb with all the bullshit he had to endure. As for the bloodthirsty thing... He really only killed a majority of the GLs because the Guardians' solution to Hal's mental state was to make it worse. Give Hal more work away from Earth, really.
B) Most of his planning seemed horrific, but all Hal wanted to do, for the most part, was to just reboot the universe and bring back everyone who died. Coast City -and- the GLC, but without any of the idiotic Oans and their braindead decisions.
