I sought to teach my daughter, then six, on the way to school one day. It was during the days of the Ethiopian famines when it was difficult to avoid newscasts featuring some of the terrible scenes.
She looked up at the sky and said, "I wonder if God is up there behind that cloud"
Seeking to teach, I said, "God is not like that, God is everywhere." To which she said, " Cor, he must be a big bloke! "
We wandered on, and then she said, "Why did God create wasps?" and I got the gist of her question. A few days before a picnic had been invaded by a few wasps, diving down on the jam sandwiches, causing fear and misery.
"Ah" says I, "we must not judge the worth or value of anything based upon how much we like them ourselves. There is a reason why everything has been created."
We walked on for a minute or two, then, having thought to herself, she asked:- "Why did God create the people of Ethiopia?"
Not sure exactly how I responded, but in answer to the OP, we must try to love them as best we can, perhaps try to teach them. But they will have their own questions, perhaps ones we have never asked. And, if lucky, will find their own answers. Not ours.
