It's the best case scenario because then only the ones who causes this mess get punished. The realistic version is that we're dragging most of the biosphere and millions of other species down with us, completely changing a stable Earth environment to something we're not even sure about.

And we can blame his work in part for that acceleration, but in truth it was already heading that direction for decades, longer than most of us have been alive. It just took a while to see the evidence of damage, and when we did, it was covered up, turned into propaganda for profit, lied about, and mostly just shrugged as someone's future problem. Well, the future is now, and not much has changed, except the environment. Humans are stupid.
