Transparent Things and Oscar Wilde

When the character Monsieur Wilde is introduced in Transparent Things in chapter 25 i immediately thought of Oscar Wilde, since the spelling of the last name was the same. Knowing that this is Nabokov and nothing is purely coincidental I have been on the look out ever since for some thing relating Oscar Wilde to this text, and since my knowledge of Wilde is pretty minimal it took me quite a while. But recently I was looking through a poem of his called " The Ballad of Reading Goal," the work is inspired apparently by a hanging that Wilde witnessed of a man named Charles Woodridge who was convicted of killing his wife. Then I came upon the stanza: "Yet each man kills the thing he loves
By each let this be heard,
Some do it with a bitter look,
Some with a flattering word,
The coward does it with a kiss,
The brave man with a sword!"

This immediately stuck out to me as something that did not just pertain to Transparent Things but also to Lolita and Pale Fire. It would seem that in all of the novels that we have read by Nabokov the fate of each of the character is to " kill the thing he loves." Humbert Humbert in this scenario is certainly the coward who does it with a kiss, as he destroys Lolita. Kinbote or Botkin seems to kill John Shades work which he loves so much in a sense "with a flattering word" and I'm not sure if Hugh Person fits into one of these categories but he kills his wife who is the thing that he loves the most. I would like to look a little further into this poem and its possible ties with Nabokov but i thought it was interesting that his mention of Wilde was able to sort of reveal a common theme in not just this text but the others that we have read as well.
