I know what you mean.

I was present the night my high school buddy blew off his right hand while assembling a pipe bomb. No, it wasn't a political act, we were just being boys.

I wasn't hurt myself, but I quickly lost my enthusiasm for things that go bang.

As for W v B, that's why I included the adjective "ruthless" in my description of him. Yeah, he worked for the Nazis, and then he worked for the USA. He had no trouble switching sides, betraying his country or his humanity. There was only one priority in his life. He had a mission, and that came first. And no one doubts he would have worked for the Soviets, either, if they had gotten to him first. A lot of his colleagues did. Oh, and yes, he exploited slave labor to build his rockets, too. Thousands died horribly helping him achieve his dream of space travel.

He was a man on a mission. Beware men on a mission. Especially if you share their mission.
