I would hope, if I were ever to be labeled a 'sociopath,' it would be on the basis of some psychoanalytic examination over some period of time (in person) by a qualified professional and not based on snippets of video and/or rumors about my activities as seen by (and imagined by) armchair and uncredentialed lay folk.
That said, it must be pointed out that not everyone involved in a homicide is a sociopath, and not every sociopath commits crimes, let alone homicides. So using that label for AK and/or RS may be hyperbolic, at best. It does nothing to further the understanding of the evidence in this case, and it is that very evidence (some of it, anyway) that casts doubt on the assertion of guilt.
This is a discussion board where such topics are not only appropriate but expected.
The accused is jailed and open to speculation according to TOS of WS.
All imo
