Benedict Arnold was a war hero, wounded in battle--before he turned against his country. Hitler was likewise a decorated and wounded veteran of the First World War. Being a war hero is not a lifetime. . . exempt[ion]. . . from responsibility for what you do thereafter.
I have an older brother and an older sister - and they had the time of their lives at university. They were at Newcastle and Edinburgh. Looking up to them the whole time, I wanted to go to university and live the life they were living, having a blast, and I didn't get in. I didn't get into any of the universities I wanted to go to.
