So? That's the boss's problem to deal with. You owe the company absolutely nothing beyond your contracted hours in exchange for your contracted salary.
You owe common decency to other human beings trying to act decently.
If your boss happens to be a cog in a broken machine, treating them like it's their fault isn't fair to them or you.
Of course, you can always quit (and usually should). But failing to determine root cause and mis-blaming your boss is about as useful as screaming at the gate attendant when your flight gets a weather delay.
You only owe it to them so long as they do it to you.
And someone who by choice decides to be (or remains) a cog in the broken machine, specifically at the point where it requires being nasty to someone, is fully responsible for that action and its consequences.

I say this as an employer.
