5 shocking WWE betrayals we still haven't gotten over

2: Why Eddie why?!

The war between these two former friends included an epic Ladder match at Summerslam 2005.

When Eddie Guerrero and Rey Mysterio found themselves without a match at WrestleMania 21, the Tag Team Champions decided to face each other in a match that Rey one.

And when Mysterio won the subsequent rematch it was clear that this irked Latino Heat greatly.

Eventually, tensions boiled over, and fans wondered whether the two would ever see eye-to-eye again.

Following an attack on Rey by MNM, things did seem to be turning around, as Guerrero would make the save against the two young stars.

What could've been a heartwarming moment quickly turned to horror, as Guerrero attacked his so-called best friend, leaving Mysterio a broken mess.

Feuding with his former partner, more losses would continue to eat Eddie alive until he finally got a win in an epic steel cage war on SmackDown.
