Also hitler as a young man served in the great war, and his battalion were absolutely decimated in "the Ypres massacre of the innocents", there's no telling what seeing that kind of carnage up close does to someone who has already had a abusive childhood. Must have been horriffic for those young soldiers on both sides.

Its not an excuse of course, as the vast majority of people who have these awful upbringings don't go on to do these things thankfully

I've read that Hitler served well and enjoyed fighting in WW1. Apparently, he never got over the defeat and especially the terms of the treaty of Versailles.
