Removing spells that return someone to life only solves the "danger" issue if the only "danger" you present in your game is death.
I don't know how many pla...er...characters I've horribly mutilated. And it's AMAZING how pla...er...characters will react to things like losing a hand, an eye, being stripped of levels, magical gear, compared to being killed. Generally speaking, one of the reasons I don't like to kill characters is because death isn't actually very dangerous.
Living on the other hand, living is very dangerous. Especially when you've got a broken leg, are moving at half speed, and just got 3 fingers bit off forcing you to make a spellcraft/arcana check each time you cast! The lengths that players will go to to see their characters restored as quickly as possible is patently astounding!
One time, I infected all the players with a "negative energy" curse. It would build 1 point of negative energy within their bodies per day until they had enough negative energy equal to their con score, and then they would perma die. Then, that night I had them all visited by demons in their dreams offering each of them the chance to save their friends, in exchange for that PC being later bound to kill one person (who wasn't one of the just-saved party members) per party member they saved.
There were 5 players.
The next morning there were 4 demonic pacts.
And the demons presented them with a list of 20 targets.
-The DM (me) subsequently laughed manically.
It was probably one of the best moments of the game. Sadly, all the characters died shortly thereafter in an unrelated prison-break...except the one who didn't make the pact. Which just meant their souls were placed into the service of these demons until their pacts were fulfilled.
So to sum this all up: death really isn't dangerous. I highly recommend mutilating your pla...er...characters instead.
But then, I'm a cat...so what do I know.
