I think the reason he killed himself is he was petrified at what the Russians would do to him if caught alive.
Which, of course, had nothing to do with the death of millions of Russians.
If the Americans had reached the middle of Berlin first, he would have been frightened of them too. Remind me again why they were after him? Was it something to do with people dying? In their millions?
As a result of the German Reich? Led by Hitler?
Words fail me.
