Caliban, and Scion, I think we have had this debate before.
To answer Caliban's question: the point is, Barbarians gain 2 * level = hit points during rage.... At high levels, even more. Without the rage, they would already have been dead from the punishment they recieved, before they even fall unconscious. How is this then punishing them? The glass can be seen to be either half full or half empty. But coming from your position, then yes, my "intepretation" of this aspect of the rules may seem "harsh". That similar risks comment is...not really called for. We were discussing Barbarians, and their rage.
It is not explicitly stated in the rules, although we can infer various things from them. Crothian and Shilsen made the strongest point, and perhaps, by the RAW, they are right.
Dr Rictus,
When it comes to accepting Raging and "refusing to die" I don't see it that way... They are already postponing their submission to injury, by the added hit point buffer they gain. It is an artefact of DnD, that all characters function normally until they reach 0 hit points.
