I got this.
Bad/evil is any action that harms society or life in society. That's because we, humans, gathered and created this "connected" style of life. What we do do not affect us only, it affects other people as well. So, if you do something that harms other citizens in any way, your action was bad/evil.
As for your answer: yes, it's bad. Even if they are much more richer than the average population, if they worked honestly for that or their family did, they deserve the money. So, taking it away from them, even if they have a lot, is a harmful action.
The "robin wood" style doesn't fit. Taking away from the rich to give to the poor(if that was the inner point of this thread) an't solving the problem.
What will the poor people that don't want to study or work(and believe it, there are so many in my country) do after the money ends? You'll have to keep "feeding" them while they sit in their couch and do nothing? And when the rich people starts to run out of money? What will do after that? Take away from the middle class? And after that?
My point is: Giving money for that kind of people(poor that do nothing) will just make it worse. They won't learn how to spend the money, they won't care how they spend it, they will become more and more "lazy".
