Hera, no doubt, is misunderstood. Hera evolved. Throughout time, as one culture conquered another, their gods were absorbed into the ruling culture's pantheon of gods. The chief god ultimately became Zeus. The problem remains: what to do with all those wives of previous "chief" gods who evolved into Zeus? Consequently, the chief god ended up with all those former wives. Zeus may have had a previous name before he was absorbed into the Zeus figure. All these chief gods had wives. The wives survived as individuals. The chief gods melded into one chief god, for there can be only one chief god in surviving cultures. The wives' stories were passed down, but they became known as wives of Zeus, no matter who their husbands started out being. Naturally, Hera is going to be jealous of so many of her husband's wives. In actuality, many of these wives attributed to Zeus started out as the wife of a former chief god. I hope I'm working through this well. . . Edith Hamilton touches upon this phenomenon. Hera has become a composite of all these wives and their personality traits. I think she's one amazing woman.
