This is a crude article (‘hundreds of millions of Jews’ — what the heck?), but as a summary of the subject it works well.

After enlisting in the [NSDAP], Dirlewanger was accused of the rape of a 14-year-old girl. He had his doctorate degree stripped, went to trial and was convicted, and even served two years in jail for the assault, but none of the repercussions did anything to slow him down.

[…]

To entertain his soldiers, Dirlewanger would torture prisoners at the concentration camps, injecting young women with strychnine, a neurotoxin that causes a violent, painful death. He would order hundreds of children to be slaughtered at once, but in the interest of saving bullets would order the executions done by bayonet and rifle butts.

During the unit’s time in Russia, Dirlewanger would burn women and children alive, and then let packs of starving dogs feed on them. A horrific rumor surfaced that he was cutting up Jewish women and boiling them with horse meat to make soap, though no SS officers ever confirmed [this].

The Ustaše would have admired him (assuming that they didn’t already).
