I wish I could rember the name of a short Science Fiction story I read once. It was about the birth of a baby boy who had strange powers. His intelligence was very low, but he could read minds, he could make things happen just with the power of thought, and he could hurt people just by using his anger.
At first, it was just his mother who suffered, getting pain if his least wish for milk wasn't granted at once, and as he grew stronger, so did the pain he could induce whenever he was angry, until he killed her. Others undertook his care, but they were punished too if they didn't instantly do his will, or even had angry thoughts about him. The cemetery filled up with people who had crossed him, or imagined crossing him.
Some neighbours tried to kill him, but he read their minds and despatched them. Outsiders made plans too, but he could read their intention - or even the intention of someone who planned that someone else would carry a bomb with a clear mind because he didn't know that he was the assassination tool - and once he discovered where they came from, he made their part of the country vanish with all it contained.
This continued until all that was left was his own village, populated by those who did everything he wanted. The cemetery now had no space at all, which someone explained to him. So he sent the corpses of people who annoyed hm to under the cornfield, where they helped grow the corn which was the only food for the few villagers that were left. The village and cornfield were surrounded by a cliff, with absolutely nothing outside that - he had willed everywhere and everyone else into oblivion.
I don't remember any happy ending - I suspect there wasn't one - but at the time the thought of someone having absolute power without either the intelligence or the empathy to use it in a humanitarian way made me shudder.
