That’s the thing with the radioactive waste and it being still dangerous for many thousands of years… We humans manage to ruin the planet within a fraction of that time already. How could we ever manage anything correctly, let alone something that requires attention for tens of thousands of years. It’s like the ultimate technical debt. A burden we can’t handle, among many other problems we also can’t handle. Collectively speaking.
Some of the better RPGs allow you to play as an evil guy (equally fleshed out as the good guy playthrough), e.g. Baldur’s Gate 3 (it even has a special evil background storyline called The Dark Urge) or (some of?) the Mass Effect titles.
Cult of the Lamb is also a great game where you play a cult leader. Although the game’s design is strong on the entertaining/funny side, it’s kind of dark also.
Stellaris is a grand strategy game where you can play anything, from a ruthless ruler trying to destroy the whole galaxy to a pacifist trader.
