I understand that it was always going to be immoral to fire bomb Dresden but the wind on that day whipped up the fires considerably and the extremity of the outcome was due to chance rather than vindictiveness. Of course I think if they’d have known the outcome of course they would have done it anyway.
Or maybe some of them considered the wind fortuitous. I wouldn't be surprised. But then, I'm not a huge fan of war. In fiction, sure. The bloodier, the better. But not in reality, where so many die to make points.
