Human beings have tremendous power in the world of Berserk. They literally created a god, the Idea Of Evil. They willed the IOE into existence.
The IOE created the behelits, which led to the creation of the Godhand and the apostles.
I think you are misinterpreting how things work in Berserk. Humans did not create the Idea of Evil (which we still can't assume is canon, since Miura decided to remove it, but still). The Idea of Evil birthed itself from the collective unconscious desire of mankind for a reason for all the suffering. Assuming this, most humans in Berserk don't even know that there is an Astral plane, let alone such a deity, or a collective unconscious. The Idea of Evil is more akin to a Tulpa (a thought form) than a god itself. Humans did
not willingly birthed it into existence, as you mentioned. It was born from their unconscious desire, which is
vastly different, and that is a hint Miura gave on how the astral realm seems to work in a sort of way. If you assume this, then just as how humans lost faith in their old gods, as mentioned by Schierke in the village of Enoch, does that mean humans have slain those entities? I think you are misunderstanding how the Astral Realm works.
It is also not mentioned that the IOE created the Behelits. Griffith sees what
looks like multiple Behelits coming from the abyss, and the IOE says they are "droplets of ideas spilled from this world to eternity". One could assume that when a man sheds his last tear, with enough suffering, it drops into that dark ocean and seeps back into reality. Again, you are assuming the IOE created the behelits, which is never mentioned.
Griffith considers all old, experienced magic users to be a threat. Why? If he is truly invincible, no magic should be able to harm him.
No one said Griffith is invincible. It is quite obvious that he is mortal, and quite possible that other God Hand members have died or been discarded.
Guts and Casca are still branded, their "safe haven" options are very limited. Skellig Island was never a long-term solution.
The Bakiraka Village is another option but it's also not a long-term solution. You don't really expect Griffith to allow other safe havens to exist in the world, safe havens that could someday become a viable alternative to Falconia, do you?
Falconia is not an option for obvious reasons. Do I even need to explain why?
I have no idea what you are talking about here. It makes it seem like you think I want Griffith to win. I am saying a direct, final battle will amount to nothing. This is not a shounen.
Even if Guts sincerely wanted to forgive Griffith, post-Eclipse Griffith is irredeemable.
Forgiving him would amount to nothing as well. Guts and Casca would still be branded, and humanity would still be doomed.
He is a psychopath and 100% evil. He is a servant of an evil god, a god which exists only to give humans reasons for pain, suffering, sadness, etc.
This is my personal interpretation, but Griffith and Femto are two different entities for me. The Griffith we knew died the moment the hand closed at him. Femto is a different persona devoid of any kind of feeling. But again, that's my assumption. I simply cannot see the Golden Age Griffith as a 100% evil psychopath.
A final, decisive battle with Griffith is inevitable.
Again, your assumption. Griffith could cause his own downfall. Kind of a touchy subject, but what if
The supernatural power of Guts' sword is an incredibly important plot device that wasn't introduced for no reason. It is not only capable of wounding and eventually killing any astral being, it can even be enchanted with elemental spirits. That's really important.
Where did you get that information from? It can't kill "any astral being", since he clearly couldn't even touch Griffith with it. Femto exists in another dimension, and the Griffith you see in the physical realm is but a projection of him, like a shadow. Guts can't touch him, he can't wound a shadow, that's not his real self. But this, of course, is how I see it. I don't remember it being mentioned it could be enchanted with elemental spirits, but even if so, still think the Godhand is untouchable as it is.
Also, Griffith has a critical weakness -- the Moonlight Boy.
Expect Guts' and Casca's child to play a huge role in the final confrontation with Griffith. I will not be surprised if the Moonlight Boy will somehow be the cause of Griffith's death. It will be a perfect and well deserved ending for Griffith, i.e. the woman he raped gave birth to a supernatural child and this child caused his downfall.
Yes, I agree with that. I am certain the Moonlight child will play a pivotal role in Berserk's ending.
That's not what we see in Berserk.
There is a big difference between child Guts vs 15 y/o Guts vs 19 y/o Guts vs 21 y/o Black Swordsman Guts.
Why would a young adult Isidro, who is now a much better warrior and can properly support Schierke (and other mages) on the battlefield, "not make a difference"?
Because, again, we are talking about interdimensional entities that cannot even be touched, let alone be wounded or killed. Beings that, again, can manipulate matter and possibly space and time. Not even considering the IOE here, as that would entail to it controlling causality. Good luck fighting that.
Skull Knight is a thousand years old at least, is but a casket with a soul inside, wields supernatural weapons, and couldn't even touch Void once he entered the Eclipse.
But again, I could be completely wrong.
