Well Rupert Murdoch's still alive, so probably him.

McConnell or Murdoch are the most destructive, though I see them more as amoral and self-interested than morally evil.

There are plenty of people who "represent everything wrong with America/the world" but again, I think those are opportunists just working for self interest.

I'm not sure I could come up with who is today's Moloch.

Putin

McConnell is my choice. His policies have led to the deaths of millions over the course of his career.

Leonard Leo?

• The strategist behind our current SCOTUS conservative super majority. Roe V Wade NEVER would have been overturned without his meddling and influence peddling.
• LITERALLY leading a right wing conspiracy of rich people and powerful politicians with the goal of taking over the government.
• Working on a new project to "apply the strategies that have worked so well to advance the conservative political and judicial cause to reshape all of American culture and society."

Trump?

Murdoch?

Dick Cheney?
