This is intended to be an out-of-universe question
I recently learned of Thanatos the Greek god of death, and I could not help but notice how similar the name Thanos is to the name Thanatos. This got me wondering if the original writers did this intentionally, especially considering Thanos' relationship with and association to death (and Death) in the comics.
Is there any indication that the similarity in names between Thanatos and Thanos is more than coincidence?
