OJ didn't even get this kind of immediate reaction of pure disdain. I love Karma! She does not play around. She really doesn't.
OJ Simpson did not get the universal disdain as it was more racial and he was once respected. Of course things have changed. Also, Simpson did not kill a child like Casey Anthony did. Anthony is getting the same level of disdain that Osama bin Laden, Lori Drew, and South Hadley 6 have gotten.
The most vilified people on the Internet and outside I have seen are:
Osama bin Laden-No explanation needed.
Casey Anthony-Probably right now.
Lori Drew-Most vilified outside of Anthony and bin Laden.
Fred Phelps-Been vilified for years.
Joran van der Sloot-Same as Phelps.
South Hadley 6-Some alleged they are the most vilified people on the Internet, more so than Anthony and Drew combined.
Jerry Sandusky-Challenging Casey Anthony.
Jennifer Petkov-Sentiment against her is negative.
Michael Crook-Most hated troll.
Michael Vick-Really angers animal lovers.
Bernie Madoff-Biggest scammer.
I go by sentiment of them on the Internet, mostly blogs, forums, and social network.
This one says Lori Drew is the worst person and eclipsed bin Laden and Adolf Hitler.
