Ok, but if karma isn't worth mentioning, why mention it in the first place?
The only thing I don't get is why people (not only you) desperatly want to kill Ben? If you don't want him in your group, which I totally understand, there could still be the hope to ditch him. What danger would he be later on, and even if... kill him then.
Thing is that in MY world I am not into killing people, not now, not in a ZA.
