To be fair though, [MENTION=54690]outsider[/MENTION] makes a point. Players can get very, very shirty when the DM starts overriding character elements. I've heard it described as the "golden box" around a PC. The DM controls pretty much everything in the game world but, the only thing the player actually has any control over is that one character. Which can make some players very, very jealous in their protection of that character.
There's a very good reason that a lot of the "I take your character away from you" stuff has been left at the road side over the years of D&D's evolution. Level draining, permanent effects, and the massive reduction in the power of Charms and the like have really changed what direct influence a DM can have over the PC's.
Whether that's a good or a bad thing I leave to the reader. Personally, I think it's a good thing. It's far, far too easy for DM's to forget that the players only can control that one thing and run roughshod over the players, making for some pretty hard feelings around the table.
