Quasi-Philosophical Musings

When we are crippled, we use the crutch to support us. With the crutch's support, we slowly regain our balance and strength to walk. Then, once we are fully fit and don't need the crutch any more, we throw it away.
Are we being ungrateful to the crutch in not using it any more? Or are we repaying the crutch back in kind by fulfilling the very purpose of the crutch in enabling us to walk straight and properly?

PS: I was prompted to write this bit after reading about some people suggesting that the BJP should dissociate itself from the RSS, though the analogy is not entirely relevant.
