[Death Note] Are shinigami obligated to do the eye deal?

Nope. They don't have to offer or accept the deal, its just that half of someone's lifespan both gives them extra life for themselves and shortens the time it takes to get their deathnote back. Plus, all the extra killings means more life for them.
