Inu Yasha Character Study: Episode 18

The hell-painter obviously is similar to Naraku as both use minions and both were consumed by evil, whether by a more direct form from thoughts or from powers of the Shikon no Tama to give him whatever he wanted. Also, the great evil that consumed the hell-painter is similar to the death of Onigumo into Naraku. An evil so tempting that death would be worth it.
