Considering how much was on stake I think somebody could have sacrificed themselves to kill Hitler.
In the end they all ended up dead.
We usually associate suicide attacks with acts of terrorism, but in some ways they may be ethical, even heroic. After all, instead of having a bigger bomb, to assure destruction of the evil dictator, you can approach the evil dictator closer as you detonate yourself. These would ensure less collateral damage, like to the soldiers guarding outside, or civilian servants.
Of course, to kill yourself, besides being very dedicated to a cause, you need to have a religion that allows it, or preferably rewards it (e.g. Islam)
Alas, German Catholicism or Protestantism, Von Stauffenberg believed in, didn't cut it !
If you watch History Chan. Documentary in the extras section, you can see that all asssination attempts failed due to some evil demon watching over Hitler. Twice, members of the German army tried to blow themselves up along with Hitler. And both times Hitler avoided their attempts by rushing through the event or not showing up. Resistance best chance would have been to have a bomb expert with Staufenberg who would have advised him to call of the assasination attempt if he was not able to ignite the two bombs or postponing the attempt until Hitler was in his bunker.
For your information, the religion of Islam does NOT allow or permit suicide. Don't mistake trouble in some country as a part of a religion. It's like saying Christ allowed abortion right? Just because certain people do things, it does not mean it was permitted by their faith. Get some knowledge before making such comments about a major world religion.
That, friend, appears to be the favorite flavor of nearly every average-Joe comment I've seen on the 'net; after all, why look for truth in anything when you can just make up whatever you want without being held accountable?
Too many apparently still believe that being 'online' means you enter a make-believe world where you can be anyone and say anything.
You can literally take any religion that has been around for a while, and turn it evil by only focusing on those who stain it.
For example, let's run through Christianity.
Hitler tailored Christian views to suit his actions and justify his means (while Pope Pius XII did nothing to hinder the Holocaust), then we have events such as over a dozen aggressive Crusade campaigns (including one of just women and children), Christian terrorism (Ireland, 'The Troubles', British Reformation, African and the Seleka militia, Tripura's National Liberation Front, United States Ku Klux Klan, Norway attacks, etc), the Spanish Inquisition, The extended slaughter of natives in North America, the Salem Witch Trials, etc.
Then we have such Christian gentlemen as David Koresh, Gary Ridgway, Bruce George Peter Lee, David Berkowitz, Sampson Kanderayi, Jeffery Dahmer, The Yorkshire Rapier, Watts, The Sunday Morning Slasher, Ted Bundy, Jim Jones, and so on.
Lastly, I could also mention a few less-than-pleasant persecution by Christian incidents, such as widespread book censorship, anti-gay propaganda, dehumanization of women, discrimination against atheists, a long-standing global intolerance for non-Christian beliefs... and the list goes on.
Now, the intent of this was simply demonstrative: If you focus hard enough with hate and prejudice, you will *always* find the worst-case scenario in and given subject. Frequently, strong beliefs (of any kind) lead to strong actions-- and those actions are not always benign.
