These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Author's Saving Throw: After weeks of decidedly un-facelike behavior and a Running Gag of Paul Bearer dummies that fans hated, Edge made a promo about he was fighting Kane's evil with his own evil and actually acted like a face, i.e. wanting to win the World title legitimately and actually respecting the General Manager.
Crazy Awesome: How much of his character is "crazy" and how much is "awesome" varies from time to time, but Edge falls firmly into this category.
Love to Hate: The fans preferred Edge as a heel so much that his 2004 and early 2010 face runs both petered out after a few months. Of course, comebacks after long injury breaks tend to pop the fans, but he's never had much of a natural progression from heel to face when he's active. Until the autumn of 2010, when issues with the anonymous Raw General Manager caused him to become a Jerkass to more traditional heels - leading to a fitting final run for his Hall of Fame career.
Edge - spear - doesn't care - spear spear - about your accomplishments because Spear.
Moral Event Horizon: Prior to about December 2006, Edge seemed more annoying than evil. It is true that he'd already done plenty of low things - betraying Chris Benoit; stealing Lita from both Kane (in Kayfabe) and Matt Hardy (in Real Life); shoving Mick Foley through a flaming table; pinning Beulah McGillicutty in a simulated rape pose at WWE's second annual One Night Stand pay-per-view; and breaking into John Cena's house and slapping Cena's father - but it was still hard to see him as much more than just a cheap bully. He really made clear just how bad he was when he and Randy Orton delivered a Con-chair-to to Ric Flair - thus savagely bloodying a near-60-year-old man - just to piss off Triple H. A year later, when he began his ongoing feud with the Undertaker, he proved just how diabolical a foe he had become - and when he screamed at Vickie Guerrero and Chavo Guerrero (his wife and nephew-in-law at the time) that if he was going to Hell, he was taking them with him...by God, he made you believe he would do it.
Of course, this 60-year-old man seems to have an addiction to being savagely bloodied, so in hindsight…
Pay attention — this was all after Lita retired. Was she secretly his Living Emotional Crutch or Morality Chain in some way? Did not having her by his side anymore because of the fans expedite a Sanity Slippage on his part? As noted above, he certainly seemed to be even more callous and disregarding of others after she retired.
Never Live It Down: Ever since that incident, everyone involved. Edge and Lita became known as the ones that "screwed Matt", who in turn became known for "never getting over it". However, unlike the other two it did nothing to hurt Edge's career in the long run; on the contrary he went on to much greater heights than anybody at the time would've thought possible, going from perennial midcarder to one of the company's top heels.
Strawman Has a Point: His "Real Emotion" promo from the episode of Raw that aired August 8, 2005. Edge points out that the only reason Matt Hardy was now a main event star was because his girlfriend fell in love with someone who had earnt his main event spot. Whilst the promo is definitely Vindicated by History, these were still valid points in 2005. But the absolute kicker? Edge's remark that despite Matt saying he wanted to marry Lita, they were together for 6 years & he never proposed.
This promo, also with Matt Hardy from around the time Jeff Hardy was starting his mysterious attacker storyline. Edge pointing out that people didn't care about Matt, and Matt was getting involved simply to take Jeff's spotlight. While Edge didn't realize it in storyline, Those were the exact reasons Matt attacked Jeff
Tear Jerker: His farewell shoot announcing his retirement on the 4/11/11 edition of RAW.
As was his shoot on the 4/15/11 edition of Smack Down, when he left the belt in the middle of the ring.
The finale of his speech on the 4/11/11 RAW makes one feel downright awful: He states that if one would ask him to go through the whole thing all over again—the matches, the training, surgery, injuries, planes, etc. etc.—he'd do it...in a heart beat. (cries)
Vindicated by History: Edge and Lita, the actual infidelity aside. While Edge became a modern-day legend and an inspiration to other wrestlers, including (especially) Ryder and Hawkins, and Lita was missed more and more as the Diva division deteriorated following hers and Trish's retirements, Matt Hardy's personal and professional life spiraled into what became an increasing train wreck for several years largely of his own doing, proving many of the things the Rated-R Couple had said about him during the Worked Shoot storyline.
Win The Crowd: Edge may be one of the best examples of this in wrestling. Starting off in the undercard, Edge worked his way up card, moving from being a popular tag team wrestler, to an over midcarder, before finally winning the WWE title in 2006. His career showed that patience really does pay off.
