To me, there is no risk. Destroying the world is the goal. Humans had a very bad run on this planet. Destroy. Erase. Rebuild.
Cringe take
Problem is, there probably isn't any rebuilding again or at least not to the level of technology that we are currently at. The main reasoning for that is all of the easy to get to resources like metals and fossil fuels have already been used up. So if this doesn't work out and another potentially intelligent species comes along it's going to be even harder than we had it getting things started.
.........I feel like you totally missed the point. Destroy all humans. Humans are now extinct. Erase their effects on the planet. And rebuild the ecosystem with species that are healthy for the planet.
Humans make the mistake of thinking that they are the most important thing in existence, and the world would end without them. This planet has survived countless exinctions of species in the past. It'll survive just as well without us.
