Why do people using the Infinity Gauntlet only ever use it to snap people out of existence?

Since the Infinity Gauntlet is powered by all six Infinity Stones (Space, Mind, Reality, Power, Soul, and Time), I'd use it to re-create the universe to be as benevolent, kind, and enjoyable as I could possibly imagine. We'd efficiently harness the immense power of countless suns to provide limitless energy and harvest dead worlds for resources, meaning no one would ever need to go without food, water, clothing, or shelter again. Then I would give everyone perfect health and make death a completely optional thing, etc. I'd do my - admittedly limited by human limitations - absolute best to basically create a vision of heaven.
