The MDL pile on was absolutely deserved, and for a number of reasons. First, it was (I think) an attempt at humor, and that it failed so spectacularly is the first strike against the comment, no matter the content. Failed jokes are often targets of derisive commentary here. Secondly, it demonstrated a really stunning lack of judgement (one should probably never suggest they understand/sympathize with the motivations of a murderer, especially one that attempts to murder kill their girlfriend and unborn child). Thirdly, I think there's a decent argument to be made that killing someone with whom you were socially and romantically involved is far more disturbing than killing a virtual stranger. Both are extraordinarily disturbing, but to me there is an extra degree of hatred, anger and psychopathy to engineer the execution of someone you were on a date with earlier that night. Others may feel the same about murdering a stranger who hasn't really aggrieved you in any way.
However, as SJH points out, Carruth wasn't the person who actually killed his girlfriend, while Hernandez is (allegedly) personally responsible for the deaths of at least two, maybe three, people. So, on that point alone, Hernandez wins the "Worst Murderer to Ever Play Major American Sports" award. Congratulations, Aaron! For your work in this arena, you will receive a lifetime of incarceration with no hope of ever getting out!!
Rae Carruth, btw, will be back on the streets in about four years. Hide yo' kids, hide yo' wife.
