Why do so many people seem to feel that a DM somehow has a "right" to use PCs? In any campaign in which I've been involved, the character belongs to the player. It's _their_ concept, time, effort involved in creating that character, why should a DM have the authority to do _anything_ with it outside of normal gameplay?
There's a certain amount of trust and respect involved here. As a player, I put my effort into creating a character, trusting the DM to be fair to me (i.e. my character). That includes _not_ doing things like killing off my character when I'm not playing him.
To be fair, maybe your DM is using it as a plot device, and doesn't intend any "permanent" harm - still not acceptable in my mind, but not too far out. Talk to him, see what he intends. If your character is "really" dead? You have every right to be very, very mad.
