So Mr Alexander essentially, SPOILERS, both felt sorry for Alex AND attempted vengeance on him?
With how, even after, SPOILERS, he came to realize it was him who hurt, violated and possibly was indirectly or otherwise responsible for the death of his wife, he was all like "My poor boy, another victim of modern age" - obviously showing his disdain towards the "Ludovico treatment" that he received but he was still mad and angry enough at him to play that tune gleefully and then almost drive him to suicide towards the end?
So he essentially both sympathized with Alex AND hated him, correct?
