Hitler was not really a Christian so stop using him in your arguments. As for your assumptions about those who are going to hell. Well you are absolutely correct. If they deny Jesus their is no hope for them, sad to say.
Hmmm..... Who's standing next to Hitler? I hear his name is Mussolini or something. I heard he may be a Christian? Really?

Not really a strawman, more of a red herring.
Both are pretty poor examples of "violent Christians" though as neither one really incorporated religion into their ideology, much better examples would be Franco or the Lebanese Falange.
