Once egg is added you have made meatloaf or meatball mix. Egg is not necessary to make a burger juicy or hold together. Just lightly mixing meat will make it tacky enough to hold together. What our taste buds perceive as juiciness is from fat and a little bit of the meat juices. By the time the burger is cooked, what little egg is in each patty has been cooked past hard boiled, so not juicy. This is all in my humble opinion and you are free to keep doing what you like of course.
