Most extreme example of this, which is fictional, is Thanos in the Avengers film who removes half of the human population in order to restore the planet for environmental reasons.
It’s a philosophical question but, at the most extreme end of the spectrum he considers that the end justifies the means.
We know morally this is utterly wrong. But it is troubling to see that the new wave of environmental extremists feel they are justified in carrying out acts that are harmful, may cause distress to others, are illegal, etc, and insist that they can be the arbiters of what is morally right because of the importance of their cause. I fundamentally disagree with them.
It is a terrible thing to target a family home and publicise this, and I expect Rishi is worried about the safety of his family’s.
