Great thinking, the world is full of immoral people, should we burn that down too?

No, but we have these neat things called society, and government, regulations, and laws to minimize the damage they can do.

Which ideally should try to solve problems pragmatically, rather than resorting to "excision and destruction"

It depends, we do have prisons and life sentences.

Edit:...And the death penalty, which I oppose, but has been a constant for thousands of years.

Your assumption that the two are always mutually exclusive doesn't seem justified to me.

Corporations today might be the cold. But If you kill them off you might be left with something like Ebola.

Just because something isn't perfect doesn't mean it's not the best outcome.

If you've got a better idea let's hear it.

Kill the bad actors, not the whole system. That has been historically what is done, and it works.

Edit: The Chickenshit Club is a good read which relates this in more detail.
