It is not noble to intentionally bias yourself toward "proudly dream of genocide" which is exactly what you propose is doing. You do propose to spend a lot of effort to get into the heads of perpetrators ... but there is no equivalent feeling of pressure to get into the head and reality of victims who need help, support and defense right now. There is also difference between explaining and rationalizing and what is proposed here sounds to me closer to "rationalizing" - because you start with assumption that analysis should not end in negative judgement.

The "how it came to be" in real world history tend to be fairly long complicated story. It gets to be explained and revised literally for years after the fact, as important document start surfacing or people who were afraid to talk starts to talk. Typically it starts 20 years ago, when some journalists ended up beaten and arrested and someone's business interests something.

You can in fact study history of holocaust with principled opinion and judgement that Holocaust was bad.
