Ignoring whether or not you think it was a good story, Fear Itself confirmed Odin in the distant past/other Ragnarok cyle usurped his brother's position as all-father and razed an entire world to erase all memory of him. This first razing due to the way it was written is highly questionable if it was necessary. He hid this truth for eons. To try and protect Thor from the prophecy he was willing to raze the entire Earth again without even considering other options like attacking Cul before he reaches full strength. Odin comes out not looking well to many people. Mainly thanks to destroying entire worlds.
Or do you feel Odin was fully justified to some extent. Cul's evilness gave Odin every right to overthrow him. That burning Aeshim was necessary to prevent Cul from regaining power. That attacking Earth was justifiable to some extent due to Odin panicking and not thinking straight.
I feel that Odin did what he had to on all counts. A ruler must make the hard decisions regardless of whether he will be looked on favorably or not.
