No. It means that treating everyone as if they have committed no prior sins will only end up hurting you in the end. You can not trust everyone at face value. That is why I wish people to prove themselves. I am a king, I do not like wasting my time on those that would rather get a free ride or drag me down with them. If I were that frog, I would have told the scorpion to stop being a lazy fool and simply find a leaf to float himself across on.
