It's your fault in the first place for letting your friend on it.
And please explain how losing 1% experience every time you die in a game is like a "part of the system" for the president to demand sacrifices to the spaghetti monster? That's a terrible analogy.
You can't try to remove the experience penalty, it won't happen. And it shouldn't. It gives players an incentive to try harder to stay alive. Having an item that gives a temporary relief for losing experience is fine, but nothing more than temporary should be considered.
Regardless, I mostly emphasize my first point: That's what you get for letting other people on your account.
