All living organisms move towards “good” (desire) and away from “bad” (fear), n’est-ce pas?
Is Buddhism deleterious to human survival? 
I think you mean : is clarity a bad idea? Is confusion a good thing? (for me, humans, and/or life in general)
“I” is judgment itself, the authority to state and enforce what is or is not; what’s true or false.
If I can believe I can be non-judgmental, I is a liar/believer.
If I could suspend judgment and be open, sensitive, vulnerable, and free of psychological thought, why would I not remain that way? Why would I abide psychological thought if I could suspend it?
