#2 Edge
For me, this one is the most obvious. From turning on his tag team partner in 2004 to costing Randy Orton a chance at the WWE Championship in 2010, I personally loved these, and every single one of Edge's heel turns. Not so much being in love with Vicki Guerrero but you get my drift.
He's so good at being the villain, I'd be willing to bet that it's hard to see him greet you with a smile in person. Each time he was a heel, he had that extra edginess (no pun intended). Also, people cared more about his character and were more invested in what he had to say.

The number of boos he got and the number of people that loved to hate him, will forever overshadow any amount of people that cheered him. Because he was such an effective heel, it made the fans much more emotionally challenged when he would eventually succumb to injury.
Edge will forever hold a place in the hearts of wrestling fans and will forever be known as one of the best heels to grace the stage of World Wrestling Entertainment.
