You'd be surprised. In some countries, especially in Africa and South America, people have a pretty different take on how to choose a name.

Trevor Noah talks about it in a chapter of his book "Born a Crime", as a teen he had a good friend named Hitler, had no idea there was anything weird about the name.

Long story short, that's probably his given name.

To be fair, I get the same reaction from people naming their kids after religious prophets.

Yeah, what kind of people give their kids weird names like Amos, Anna, Hannah, Daniel, Deborah, James, Jesus, John, Muhammad, Nathan or Noah.

Different parts of the world have, you know, different perceptions because of different culture and history. For example, Nazi paraphernalia are popular in Thailand because they just aren't aware of how bad the Nazis are like Imperial Japan is. Speaking of Imperial Japan, try waving the Imperial Japanese flag anywhere in Asia and you'd be slaughtered immediately. The Imperial Japanese flag doesn't really elicit the same reaction in the West as the swastika.

So, I reckon that in South America, since they never directly fought against the Axis, the names of Hitler and Mussolini are trivial to them.

People around the world have different education, if even any at all.

All they know it's a famous historical name. They probably have no idea of the history behind it.

There are countries where history and WWII in particular is so poorly taught, and instead people are heavily reliant on pop culture, especially how movies (mis)interpret WWII and thus those people think it's a huge fairy tale. So we have actual people, some places and things (there exist in India an ice cream cone product called Hitler) named after the world's worst dictators.
