Hmm, this is just me, but I find the eclipse to be by far the most violent part of the series, there were some pretty disturbing scenes in other arcs for sure, but nothing can compare to that.
So not really, no.
It's not like Miura is gradually increasing in violence with each new apostle or villain or monster that Guts is facing, the culminating point in the story so far always was the eclipse.
And if the eclipse remains the most violent part despite all that Guts went through before and mostly after, for me it means Miura knows how to gauge the amount of violence he puts into every battle.
So if none are outdoing the eclipse (which is the most traumatizing event out of them all for Guts) then for me it's not too much.
