it was because he was a kind and gentle man.
lol not to mention dashingly handsome. That's not the real reason though, one reason, I would speculate, in the same vein is that having your physical relationship with the kids being giving them candy denotes responsibility and also removes some psychological pain from the kids (and vice versa), the kids are happy as hell they've got candy (sugary shekels) and Mengele wished them to specific harm that would denote NOT giving candy to children (as a kind and gentle man), instead he treated them like he would any kid...but business is business...
For some reason every interview I've ever seen with people who knew him always mention how good looking he was
