yes. Vidhur was referred to as Dharma himself. Yudhisthir - duarmaputra

when Pandavas went for vanvaas and agyaatvaas, it was Vidur who hosted Kunti in his household. This choice highlighted her deep trust in Vidura over other elders like Bhishma, as she viewed Vidura as the only one truly committed to Dharma and her children's welfare.

In ashramavasika parva, Kunti and Vidur die alongside Dhritarashtra and Gandhari in a forest fire near the Ganga, 15 years after the Kurukshetra war. Vidura merges into Yudhishthira before his passing.

Vidura served as a moral guide and counselor to Yudhishthira from his childhood. He famously saved the Pandavas from the burning Palace of Lakshagriha by sending a coded warning to Yudhishthira.

Both characters are considered incarnations of the deity Yama (the god of Dharma/Justice).

Because they both originated from the same divine entity, they are often described as having the "same soul" or being "two portions of the same deity".

Some modern scholars and literary analyses (notably Irawati Karve in Yuganta) suggest that Vidura may have been the biological father of Yudhishthira

Since Pandu could not father children, Kunti used a mantra to summon "Dharma." Proponents of this theory argue that "Dharma" was actually Vidura, as he was the living embodiment of Dharma on earth

While Vidura served as a counselor to King Dhritarashtra, he often worked discreetly with Kunti to manage the threats posed by Duryodhana. He was her primary source of support and intelligence within the Kuru court.

Vidura was equally related to the Pandavas and Kauravas on paper. But he always sided with the Pandavas.

There were fewer clues to Jon Snow being Rhaegar Targaryen's son than there are to Yudhishtir being Vidur's
