"People really were talking about "satan worship" and whatnot, and there is really no call for that. We just don't know."
(unreal) Yeah we don't know about all that other stuff BUT we do know one crackpot girl killed another human being and dismembered her. So keep on twisting and turning and defending poor poor Sarah. Gosh poor lil ole thang, she's been through so much. Now, who was that other girl, you know, the dead one. Oh that's right lets forget about her besides she's dead now. Why bother (sarcastic and disgusted)
Victims Rights now! Don't let victims become disposable nothings.
Who is "defending" Sarah? No one has said anything like that. It appears that your formulation is that we either accept that she is a Satan-worshipping drug addict, or we are "defending" her murdering someone. To the extent you believe that, you should avoid referring to others as crackpots.
It appears that she has murdered someone in cold blood, and dismembered the corpse. We do not need to heap extra evil on her at this point in order to explain the deed. The evil embodied in her acts is quite enough.
