Dorian Gray character review

Dorian Gray begins in the novel as a young, innocent, very attractive man with good morals. He has his portrait painted and wishes to remain as young and beautiful as he looks in the picture. Unfortunately, he is easily influenced by the cynical Lord Henry Wotton, a trait which eventually leads him to a life of sinning and cruelty; but, as he had wished, he shows no signs of ageing, injury, illness or evil - instead the portrait changes and suffers the aesthetic consequences of each sin committed. By the end of the novel, Gray decides he should be 'good' again, and upon trying to destroy the portrait, he kills himself. 
Dorian Gray clearly has a deluded sense of priorities; he is so obsessed with youth and beauty that he does not recognise that there is anything more to life, and that his purity and innocence are far more attractive and special qualities, which actually lend his aesthetic a unique appeal. What's more, he enjoys being able to commit sin after sin - he loves being evil. He enjoys seeing the portrait grow more and more hideous, and his one and only concern is that someone might discover the painting and see what he really should look like.   Ironically, even at the end of the novel, Gray still shows a sense of naivety (or maybe stupidity?), by blaming youth for his cruelty. 

I thought that this quote summed up Dorian Gray extremely well, and perhaps explains how torn Gray is as a character: 

'Dorian Gray is so many opposites at once that we can't really try to understand them all. He's good, he's bad; he's beautiful, he's hideous; he's perfect, he's terribly flawed. Most importantly, he's literally two things at once—he's himself, a living, breathing human being, and he's also the portrait, a visible reflection of the state of his (crumbling) soul.' - Shmoop
