Finding truth in history is quite the tug-o-war. Some historians could also be known as cherry pickers. It is not easy to discern truth seekers from cherry pickers, on all sides of the story line. I suppose the adage "stretching the truth" was coined by an historian and not a fisherman.
A few points of distinction in your statement, the theme is correct, but:-
1. The Final Solution, was to rid Germany of the Jews ; not by killing them but by
deportation or transportation.
2. Action T4, was to rid what the doctors described as useless eaters.
3. Eugenics, originated in the UK and America before 1930 and adopted by Germany.
4. Concentration Camps, were inaugurated by the British in the Boer War 1899.

A good maxims to bear in mind.
Winston Churchill said; History is fine if, only half of it were true.
Also the truth must be protected by a bodyguard of lies.
