Well, it is very clear that we're all biased to a greater or lesser degree. But frankl,y I think this discussion has become pretty pointless because we essentially have two sides and neither one is gonna change its point of view. That's a fact. Personally, I think we should keep to strictly military discussions and leave the philosophical/ethical stuff for others to discuss - we simply do not know the circumstances (especially in this particular case) so we can't really judge nor do we have the right to do so in my opinion.
And no matter if he was killed or executed, it was an illegal action. Would it have been legal, he'd been tried again (which obviously wasn't possible since he'd been paroled already) and punished acoording to teh sentence. If he wasn't just killed by some fanatics or ex-resistance fighters but somehow the government was involved that only makes matters worse. Much worse. We Germans wouldn't care, though, because my country doesn't want to have anything to do with those people, especially no SS members. [sarcasm on] We all know they were all vile criminals to the last man, don't we? [/sarcasm off]
P.S.: What do Kamikaze pilots have got to do with this, by the way?
