Conservativism has its place, no issue with that, but the AfD is crap. If you are a conservative in Germany, there are enough decent parties to vote for.
And while the NSDAP did have a socialist element especially in its early days, that was very much pushed back (and its representatives even murdered) as Hitler and his clique rose to power. Of the leading Nazis, Joseph Goebbels was probably the only one with some socialist views (as a young man he had dabbled with joining the communist party), he was therefore never happy with Hitler turning against Stalin (whose ruthlessness he admired), viewing it in 1945 as the one giant mistake breaking the Nazi camel's back.
But Goebbels' influence on the Third Reich is historically widely overrated, Hitler didn't trust him in military matters at all (Goebbels had never served in the army due to his birth defect foot) and held his socialist leanings in check. Goebbels' diaries are full of moaning and whining about Hitler not keeping him informed about war developments and not following his recommendations for wartime domestic policies (Goebbels wanted a tough wartime economy and social life, Hitler, wary of how quickly Germans tired of the war during WWI, tried to preserve and even better pre-war standards of living in the Reich all through WWII). Germans weren't really faced with the dearth of a wartime economy (quite unlike the rest of Nazi exploited Europe) until capitulation in 1945. Supply logistics in the Reich worked well as late as 1944 - things only crumbled in the last six months od the war, but hunger was something Germans only began to experience after the war, especially during the cold winter in '46/'47.
Goebbels was relegated and more and more sidelined as the war went on (would you believe that he only found out about the German attack on Russia in 1941 AFTER it had actually begun?!). However, his irrefutable propaganda talent regarding his own self-promotion (and not just Nazi goals) kept the public in the dark about his continually reducing role. Within the inner party in, say, 1943 he was already a marginalized figure and perceived as such. And he knew it and complained about it, but never lost his almost religious loyalty to Hitler (interesting for a man who was a professed atheist - never mind his Jesuit schooling and his arch-Catholic family upbringing - and generally had an intellectual, if utterly cynical perception of things).
