you kind of answered your own question with what you said...
can you imagine if whoever was to induct benoit would say...."although he murdered his wife and son, he was a great technical wrestler" ???
do you know how retarded that would sound and how awkward it would feel? never will he even be thought of for a Hall of Fame induction...
just like he is not even thought of in wwe records/ppvs/video games merchandise etc.
