That is exactly what you should be thinking at this point because when he gets home, he sees the painting, and it has a cruel smile on its lips. This is when he realises what has happened and it begins to get worse from their. Sybil commits suicide, and he decides to hide the painting. he becomes a socialite and people really like him, even though they hear rumours of him doing terrible things. As years go by he starts to spend more and more time looking at his painting. He corrupts other young men, and doesn't care what people might think he gets up to, because his reputation is still intact, whereas the other young men's are not.
He shows basil the painting, and Basil is disgusted by it. He fights with Dorian and tells him to pray for forgiveness, but Dorian refuses to and kills Basil. He gets rid of the body and after that he tries to find a way of escaping. He starts to take opium and that 'helps' him.
After about 6 months, he begins to wonder if the portrait has changed, after all of his good behaviour. When he goes to the attic, his hiding spot, he realises that it is actually worse, and that the blood on his hand has spread to his other hand and on his foot. He thinks that if he just get rid of it then it will do nothing to him, so he picks up the knife he used to stab Basil and slashes the painting. When his servants come into the room after hearing horrible screaming, they see an old man lying dead on the floor, and the painting looking just as young and beautiful as Dorian had looked the day before.
