Isaiah was dead, finally.
He had suffered.
Before he died, Isaiah had truly experienced a fate worse than death. He had not died, he had been tortured to extremes beyond the imagination of an ordinary mortal.
One would think that Isaiah would have been killed long ago after his capture. But he had been alive, living in this kitchen for the past two years.
The amount of pain he experienced, even if he managed to escape or they let him go, he wouldn't be able to function properly in the outside world.
He had already been mentally broken.
From the moment he had decided to take revenge on Kael, he had doomed himself.
If he hadn't gone to Xu Ying and his group, he wouldn't have tried to take his revenge and failed.
Xu Ying wouldn't have put the Limit Seal on him.
That limit seal was the reason for his suffering.
Before he died, Kael had dedicated her time to extracting the limit seal from his body.
