When they force other characters to not abide by the rules of the game, yes, very much so. And that's something I learned without having someone to kindly write up a full wall of text for me to follow.
They have character, but if you noticed my description, those character traits are all negative. If they're supposed to be slightly immoral thorns waiting to stick into someone's side, then you've done a really good job writing them that way.
Let me spell it out for you: This isn't your game. Life isn't fair, and neither is any RP; characters can and sometimes will die, and unless you're the person running the RP, you have no say otherwise.
A Skakdi I had in an RP died in the stupidest fashion possible once I ran him through an electric field. There was a commotion as I viciously fought the moderators to keep him alive, but there was no logical way he could have survived, and I had to force myself to see that.
The same goes for this RP, this circumstance, and any that follow it.
Like I said, if you want that, you can make an RP where that is a major rule. Until then, use this as a learning tool, and if you're fearing your characters might die, learn from it, and don't get so attached next time. There's no reason not to like your ow characters you make, but when you're fighting off other characters who aren't doing anything wrong, just to ensure your character lives, you've turned your character into the problem.
