This is what is interesting about this whole fate gu theme , i myself multiple time hesitated between agreing with FY and agreing with fate gu and HC .

HC had a pretty good justification , preventing other race from having a chance to get back up and the venerable from destroying the world , it also allowed humanity from coming down .

But also you can't state humanity search for liberty and power , they will eventually want to get rid of it . There is a reason why it was mostly POIV and SCIV who took the most mesure for fate gu survival , even GLIV who lived way after variant human stood chance to get back up was actually questionning fate gu purpose .

After that you had RL who clearly disagreed with it and even in our current FJH also didn't believe in it and FJG even betrayed HC .

Fate gu is both and bad , the question is what is the meaning of you action when something like fate gu exist , it say when you have to live and when you have to die . There is no meaning for living when you whole existence can be decided by a object and no matter what you try you can't escape .

This is why Renzu went mad .
