What if they are literally running into your sword and expect to live? How would you handle this as a player?

That's a very good point. In this instance, I would say PM either the person and let them know that they would, in every sense of the phrase, be run through by aforementioned blade. Or, on the other hand, I would tell a GM, and to be honest... They're asking for it. I mean, if they go "Oh, I see what... Okay, then... let's take a step back, is that okay?" And then you compromise a fix. I believe everybody whose character is in danger of death in the moment should at least be notified and given a chance to respond before posting the death, simply because it might just be a mistake and it could very easily be a mistake the character himself/herself would not make in real life.

Good point, Kestrel.
