Or perhaps consider that if truth is good, then more truth is likely to be more good, and good people would (should) embrace truth and bad guys speaking more truth would be better than bad guys using less (as surely that is one way to measure who is bad).
Given these options (and I could go on) I'm not sure why a "noble" lie or suppression of speech are the only choices, or better choices.
The world would be a better place if we opted for Option C: embrace the truth. And if you must fight "bad guys", fight what makes them bad instead of gaslighting them.
