It's historically interesting to maybe understand who he was as a human being. He's often painted as a monster but he was a human, and is a warning to all of us what evil human's can achieve.

For example, they're revealed he had Kallmann Syndrome (which can cause a micropenis and undescended testes) - he may have essentially been essentially asexual which may explain some of his life choices and why he was so dedicated to politics and gaining power. They've also shown he had high genetic risks for psychiatric disorders such as schizophrenia, as well as ADHD, autism.

Sensationalist reporting aside, these findings do add something to our understanding of a historical figure who had massive influence on human history.
