I think there are two a bit different kind of questions in this. One is about prevention and one about recovery.
If humanity classifies itself as a “high-risk lifeform” should it cease growth or development to avoid the risk?
If aliens come to laser a couple of cities and they argue they did it to control damage humanity is doing (assuming the arguments hold), should humanity not retaliate and allow such correction?
