Why can you not use the contrapositive of rule applications in psa questions?

EBPERLOFF

Like in lesson 5 why can you not conclude that the conclusion could be morally right by using the contrapositive?

Because PSA questions aren't formulaic like SA or MBT. So when you draw a contrapositive, it's a (soft) contrapositive. So the reason you csnt say something could be morally right contrapositively on a PSA is because you're only entitled to conclude that something "isn't morally bad" or is morally neutral
