Wannsee Conference and the "Final Solution"

The Wannsee Conference began January 20, 1942. As the article relates:

On January 20, 1942, 15 high-ranking Nazi Party and German government officials gathered at a villa in the Berlin suburb of Wannsee to discuss and coordinate the implementation of what they called the "Final Solution of the Jewish Question.'"

This seems to be one the most evil deeds planned under Heydrich, and he was involved in the planning of almost all of the Nazi's worst including the Night of the Long Knives and Kristallnacht.
