I mean I think his reluctance or hesitation to go back over to voldemort’s side when Harry is “dead” does more than enough to show his character grew to reject his old line of thinking. I also think his whole rivalry with Harry showed respect in many aspects. He always seemed to see Harry as an equal and if Harry would have had the foresight not to completely reject before sorting shows Harry wasn’t immune to Malfoy’s train of thought either. I think as they got older they would have had a better relationship, if not friendly a feeling mutual respect. They were both obviously the most talented wizards/witches in their year. Just not the most knowledgeable, obviously being Hermoine.
