GOW III Ending questions - may have spoilers be warned

[jneul]

So at the end when kratos open's pandoras box the secret weapon is hope, but you have to unlock it by forgving yourslef for the bad things you have done, this allow kratos (i presume) to kill zeus at the end sucessfully, I'm just checking lol, anyway when he kills himself I am presuming it is so athena does not get the power and whatever is left of the world get's it instead (even tho it is in choas with plague's and floods etc), have i understood that right and is there anymore hidden endings, it did not tell me what happened after kratos died??.

Edit: I may have to replay this game again lol, some brilliant mindblowing event's happened in GOW III, I still can;t beleive my own eyes, lol
