In this case, no you can't. Company politics has placed a superior of yours explicitly tasked into order you to do a bad job.
I do completely agree with the "just find another job" line. What I don't agree is with that "cheer, your job is less stressing now".
If I find that I absolutely have to either cut corners or let the deadline slip, I let the deadline slip. I refuse to knowingly release crappy work, you can fire me for it, I don't care. But long before that deadline, I will have explored the options for changing the scope of the project so such a decision isn't necessary.
"Just find another job" isn't sufficient because every job involves making tradeoffs between personal goals and business goals. I believe in being real clear with management about what's happening so that we can work towards an equitable solution.
A job you love is a great thing. But that job is only going to last as long as the economics work, or the company wants it to last, or if you're doing the business end as well as the technical end. Once it's gone, just find another job and work out ways to love it.
