Ok, I'll try and explain this again.
5 friends get together to play D&D once a week or whenever as part of an ongoing campaign (I'm asssuming here). One plays a druid, with an altrusitic goal of reaching epic levels. He is not playing a combat character, and doesn't always have healing spells to hand (since he's a druid not a cleric). He doesn't close to combat because he doesn't want to be taken down or be hurt so that he has to use nessecary healing on himself. During a fight when the party should have run away (and yes, it is a superior force if they are having to hold them at bay rather than fight), the PW needs healing. The druid decides that before he does that he is going to boost his protective spells. Unfort, the PW died (because the party didn't run) and everyone blames the druid's player.
The DM in question raises the issue here to see other views on the situation, and basically gets told that the surviving party should lynch him. Come on guys, character deaths do happen. Sometimes its because of other party members, sometimes its inaction or simply bad luck.
What if it was the NPC defender who fumbled an attack, unfortunately hit the PW and did enough damage to kill him? Whould you be out for his blood as well? I don't think so.
If the other players arn't happy with that then why should that one player be grilled for it. He made a choice, regardless of his ultimate OOC motivation. The party shouldn't dump him, kill him, have him beaten up/killed...etc. Thats not what the game is about. The game is about having fun, and playing. The party I'm sure should handle this situation in good graces, as friends, but do it IC. Let the party discuss this as characters. Its not fair on that one player that he should be forced to make a new character because of this. Wheres the fun for him then?
