What contrast does Lord Henry make between Basil and Dorian?

Dorian Gray appreciated Basil as a friend. Though Basil was attracted to Dorian Gray, there was nothing deep about it since he was only in love with Dorian Gray's appearance which gave a huge change on Basil's artistic skills. Dorian Gray appreciated their friendship. When Basil finally had the guts to tell him about his affections, Dorian was already a changed man. His mind was preoccupied with other thoughts like the mysterious painting, emptiness and guilt for all his evil deeds.

He was bored of his conservative morality, and annoyed by his good advices.
