It should never be forgotten but equally important is that the truth of it should never be forgotten. There is a real danger in remembering "bogeymen" in place of people when it comes to the horrors of the past. It is important to remember but also important to understand - and the latter is something that many, understandably I suppose, instinctual pull away from.

We must remember what happened, yes.

We must also remember how easy it was for normal people to be indoctrinated into regarding other humans as less than human.

We must also acknowledge that many people did many horrific things under order, in order to protect themselves and those around them.

We must acknowledge and remember these things because failing to do so edges us closer to believing that the same thing couldn't happen again, at any time, anywhere. That there was something inherently different about people in Nazi Germany that means it "couldn't happen now" or "couldn't be us or our governments".
