I always wish people could put this into perspective but not a lot of people do. Benoit's brain, as you mentioned, was extremely damaged. It was the equivalent of an 80 year old Alzheimer's patient when he was autopsied. But so many people view him as an evil murder. Verne Gagne WAS an 83 year old Alzheimer's patient who killed another patient by doing wrestling moves on him. Both Verne's and Benoit's brains were in similar shape, but people give Verne a pass and they condemn Benoit.
So many people see the world in black and white, without looking at all of the details hiding in the gray. Often, so many answers are hiding there.
