Now that is S tier sophistry. We sure do try to fix or prevent future deaths, wherever and whenever possible.
I really, really fucking hope they don't focus on the Biwa demon too much and just get to it. Things have been going on long enough, she wasn't ever a majorly relevant character, something I hope isn't about to change, and there doesn't seem to be too much of a reason to make her so. As they said, she isn't strong, just annoying, and once her gimmick is solved it should be a quick death.
I still can't figure out how soon this is going to end. Because both a time skip / him escaping or an immediate ending here seem equally possible. Which is the better idea is the question. Or maybe we'll get a Naruto level final arc. Who knows.

I really hope that's solely devil's advocate and not what you actually believe. The only situation it isn't far fetched is if you're literally insane. Even a psychopath would understand the illogical nature of his thinking and the flaws with it.
That logic is "you should submit to the devil because it's easy, forget all the crimes he's committed, forget his evils and cruel personality and the fact that he could and would murder you at a whim, just take the 'safe and easy' route of procrastination and hope nothing changes, hope he decides to leave you alone and he doesn't decide to enslave you all and murder you and eat you.". That comment of yours was literally the justification every dictator uses to try and dissuade people from revolution.
Parasyte isn't even close to the same thing. Symbiosis of sentient, but threatening, creatures which you've had rivalry / war with, isn't even close to living under the thumb of a literal demon / god. At least there they could defend themselves and had potential benefits.
