In two of her last speeches before she is led away to be entombed, Antigone suggests that Creon is responsible for her death. She says,
But if the guilt
Lies upon Creon who judged me, then, I pray,
May his punishment equal my own.
In the utterance above, she does not out and out place responsibility for her misfortune on Creon, but she strongly implies that this is the case. She says that if it is true, she hopes he is punished as harshly as she is.
Shortly after this, she says,
You will remember
What things I suffer, and at what men's hands,
Because I would not transgress the laws of heaven.
Again, she does not precisely accuse Creon, though that is her meaning, saying that she suffers at "men's hands."
The important point is that Antigone understands that neither she nor the gods are to blame for her misfortunes. This is solely the responsibility of "men," most pointedly Creon, for overstepping the bounds of their worldly power. In refusing Polynices a burial and passing the death penalty on Antigone for defying him in this matter, Creon has offended the will of the gods. Haemon tries to impress this on his father, but to no avail. It is only when Tiresias tells Creon that the Furies will unleash their wrath on the city if he does not right matters that he decides, too late, to free Antigone.
Creon's guilt is made clear as his family members kill themselves and he is left alone and bereft, with no reason to remain alive.
