Voldemort could feel no love due to the fact that his (witch) mother conceived him when his (muggle) father was under the influence of a powerful love potion. The love potion cannot create actual love, only infatuation, something that was addressed by J.K. Rowling when she said something along the lines of;
"this would be the result of such a loveless/evil union".
Is there any evidence to suggest that the love potion (or anything else about the manner of his conception) made him preternaturally powerful at magic or augmented his intelligence, handsomeness or otherwise any other skill or capability?

Ravleen: How much does the fact that voldemort was conceived under a love potion have to do with his nonability to understand love is it more symbolic
J.K. Rowling: It was a symbolic way of showing that he came from a loveless union – but of course, everything would have changed if Merope had survived and raised him herself and loved him.
J.K. Rowling: The enchantment under which Tom Riddle fathered Voldemort is important because it shows coercion, and there can’t be many more prejudicial ways to enter the world than as the result of such a union.
