Who performed ten labors to atone for his wife's murder?

The correct response is Heracles, notably known for his significant role in Greek mythology as a hero marked by immense strength and bravery. The ten labors he undertook were a penance after he was driven mad by Hera, resulting in the tragic killing of his wife, Megara, and their children. To regain his honor and atone for this grievous act, he was tasked with completing these seemingly impossible feats, which ranged from slaying the Nemean Lion to capturing the Golden Hind of Artemis.

The other figures mentioned have distinct mythological narratives. Jason is known for leading the Argonauts in the quest for the Golden Fleece, and Perseus is celebrated for slaying Medusa and completing other heroic deeds, but neither is linked to performing labors as a form of atonement for murder. Odysseus, the clever hero of Homer’s "Odyssey," embarks on a long journey home after the Trojan War, but his story also does not revolve around a set of labors resulting from a personal crime. Thus, Heracles stands out as the only figure associated with the specific context of performing labors for atonement.
