What is your nature?

Story 1:

The Scorpion and the Frog

A scorpion and a frog meet on the bank of a stream and the scorpion asks the frog to carry him across on its back. The 
frog asks, "How do I know you won't sting me?" The scorpion says, "Because if I do, I will die too."

The frog is satisfied, and they set out, but in midstream, the scorpion stings the frog. The frog feels the onset of 
paralysis and starts to sink, knowing they both will drown, but has just enough time to gasp "Why?" 

 Replies the scorpion: "Its my nature..."

Story 2: 

Two monks were washing their bowls in the river when they noticed a scorpion that was drowning. One monk immediately scooped it up and set
it upon the bank. In the process he was stung. He went back to washing his bowl and again the scorpion fell in. The monk saved the scorpion
and was again stung. The other monk asked him, "Friend, why do you continue to save the scorpion when you know it's nature is to sting?"

"Because," the monk replied, "to save it is my nature."
