Why is lessening the survival of the species an undesirable option? Again, the “should” factor is HUGE.
And why would we be “evolved” to have to propensity to violate it if it were something hardwired?
Because that’s how life works. Successful species ensure the best chance of survival. Unsuccessful species become extinct.
I’m not sure that I agree that we have evolved to have a propensity to violate it.
