When will it happen again? I want to shoot another billionaire.

Why do you want genocide?

I would kill a billionaire with no regrets

And that is how your dream of anarcho-communism will always die. Once the killing starts it devolves into who is willing to do the most killing that wins out. Look into what happened in the Ukraine in the 1930s, an event called the Holodomor.

Which is why you're evil.

If someone thinks killing is the way to force social change then they are truly on the wrong side of history.
