Vast tragedies throughout history were perpetrated by people who thought they knew better than everyone else, that their ends justified imposing their means on the rest of the human race.
Your attitude is dangerous, because you can use it to justify anything (e.g. you think you're about saving lives). It is evil, because it places you above everyone else and leads to death (e.g. you think you're saving civilization, which requires destroying the bad parts of it).
You either have not learned from history, or have learned the wrong lessons from it and are following in the footsteps of millennia of anti-heroes.
When it comes to saving countless lives, the economy and in the most extreme of possible outcomes all civilization... YES.
