In The Picture of Dorian Gray, does Dorian Gray attempt to reform his dissolute life?

In the novel The Picture of Dorian
Gray, by Oscar Wilde, the character of Dorian Gray is a tragic antihero. His
vanity and propensity for being easily-led drives him towards a path of self-destructive
behaviors. All his actions were done under the wrong idea that life is meant to be a
feast for the senses. Therefore, he over-indulges in every whimsical taste that comes to
his fancy. 

Undoubtedly it is Dorian's impulsive behavior
that leads him to try, in three different ocasions, to reivindicate his ways and lead a
life of virtue. He fails in all three ocasions. His capricious nature prevents him from
deviating from anything that is not intense, nor perverse,
enough.

However, this aspect of Dorian's personality is
only known to us after he meets the dark influential person of Lord Henry Wooton. Prior
to this, Dorian actually was close to leading a normal life. He was even interested in
philanthropy. This plan, however, was deterred by Lord Henry's interference, where he
begins his journey into Dorian's mind by promoting a gospel of hedonism that Dorian
quickly follows.

The second time Dorian tries to change his
life is when meets a lower-class actress named Sybil Vane. Dorian's fascination with the
actress is clearly another caprice of his, particularly when he decides that he is going
to marry her. When he speaks of her, he continuously compares her to the Shakespearian
characters that she interprets. He insists that he is going to love her forever. He
basically promises Sybil the world. In turn, the woman falls madly in love with Dorian,
and decides that acting is no longer her passion: Dorian is. Sadly for her, when Sybil
acts badly one night, Dorian's fantasy of her ends and his coldness and meanness towards
her leads to her suicide.

The last try occurs the next day,
when Dorian is again touched by the idea of living a life of virtue with Sybil Vane, and
sends her a letter. However, he receives the news from Lord Henry of Sybil's suicide.
Instead of learning from this sad event and understanding the gravity of his behavior,
Dorian takes Sybil's tragedy as her final performance. He was happy that someone would
have done something like that in the name of romance. This is Dorian's turning point in
life: From this moment on, his life becomes nothing but complete
chaos.
