MrFellony, my point was that Guts was out of Fate's line since he was born. After all, he should be dead.
About Griffith's destiny: I think it was his destiny to become a god hand, since he had the Red Behelit. But Guts made him diferent. Made him unreasonable, which ALMOST made him forget his dream! Basicly what happened is like when you're playing chess, and you relying too much on a certain piece (let's say the queen - the most powerfull piece on the table) and you loose that piece. You kind of lose control. That happened to Griffith when he lost Guts.
If you think that Guts leaving wouldn't made Griffith have sex with Charlotte, I'm inclined to disagree. It might have happened AFTER some marriage, but it would happen. And Guts return, saving Griffith, and ending up to the Eclipse, would have happened anyway, since the Behelit was destined to be his. It was just going to happen in another way.
Idea doesn't control the God Hand directly, so they don't "obey" them. It shapes mankind's destiny to do it's bidding, but not directly, since it is just a product of men's fears and everything else.
I think (and here I digress a little from
psi29a) that Idea is a manifestation of human subconscious, but not all magic entities. Something most powerfull might exist (I think it exists, at least
), but something less powerfull then Idea (magic spirits, elemental entities) exist. And they can influence the world, in a better way, than Idea. So, in the end, Berserk is still Good vs Evil, only that evil is so much more prevailing (being created by manking itself).
Ok, boring post - sorry guys. If I wasn't clear enough, it's because english is not my first language!
. my rebuttal to your point khelegond is that without guts Griffith wouldn't have been as able to achieve the grandure at the peak of his glory and then crash after he left. It is widely accepted (i believe) that the reason for Griffith's downfall was his depression and lack of reasoning after Guts left him. Guts distracting him from his dream is what led Griffith to sacrifice his companions. His intense love for guts and then Guts rejection of him, IMO, caused him to want to get rid of the love he felt for him no matter what. but i cant takl now im already late for clas 
. In a way you could argue that ultimately humans have free will because the actions that they are fated to do are their "will" anyway since it was their will that created idea in the first play 
. If there was no guts, then griffth could have gone down several paths. he may have not achieved what he set out to do, he may have attained the success he did with guts under his command, but one thing for sure, he wouldnt have formed such a strong bond with anyone else he found. a strong bond that would be broken and cause him to follow the path to the eclipse
