Cutting heads off is like eating potato chips. You can’t just stop once you’ve started.

I'm worried about the very same thing. I have just yesterday read about the actual French Revolution and the Reign Of Terror that followed short after simply because - guess what - the revolutionaries couldn't stop killing people, for some reason.

It in fact even went to absurd extents, where they ended up killing other revolutionaries and eventually they themselves got guillotined themselves.

I think the lesson to learn here is to take the oligarch's wealth, but not kill them. In other words: "Tax the Rich", not "Eat the Rich".
