Venomous lizards of the desert: studies of Gila monsters and beaded lizards have uncovered an array of surprising characteristics, from odd fighting rituals, to extreme energy efficiency, to a venom useful in treating diabetes

Natural History, July-August, 2004 by Daniel D. Beck

It would be sad if these remarkable creatures disappeared. Back in graduate school; whenever I was asked why anyone would care about venomous monsters, the only rejoinder I could muster was: "They're cool!" I still think monstersaurs are cool. But after years of study I can add to my answer. Beaded lizards and Gila monsters display a unique combination of evolutionary tenacity, energy efficiency, and endurance--a solution to the problem of life unlike that of any other lizard.

From a more human-oriented perspective, I can point out that peptides from their venom are helping to treat diabetes. I don't think it's an overinterpretation of experience to say that without them, the world would be a poorer place.
