Articles about serial killers always creep me out, I feel just uneasy reading about them.
No doubt it is a fascinating subject however, how the human brain can function, even in a less than shall we say, optimized way in these cases.
The only thing I really have to add in this case, especially since it's a world war case, I always remember a quote from Schindler's list
" War always brings out the worst in people, never the good"
Or something on that line, not really much more I can add :P
