Just climb into the bottom of a live rocket during launch on a hostile planet. Then murder everyone on board, because those people were obviously superfluous to requirements. (Why send one when you can send 4?) Fly by planets in close proximity so we know where you are and pass derelict spacecraft by chance in the vastness of space. “The Sins of the father are visited on the soon” indeed. He’s not Brad Pitt, he’s James Bond.
