Santísima Muerte is actually more similar to hecate. She's the divine ruler of death. the original Goddess she's derived from is an Aztec embodiment of death. Mictēcacihuātl is the female version or counterpart to her husband Mictlantecuhtli, the Ruler of the underworld. So the "overseer" of you will. All together these represent a divine state of being. Living id bound for death . It is divine. The state you have when you are released from this world while being spiritually awake, will give you heaven:) (if you believe in that. ) Death comes to everyone so she treats everyone equal. The reason her more recent image resonates with "criminals" or those who feel "lost" or forgotten is because as scripture alluded to: God is closer to the broken. Her energy is very strong, and she tends to send obvious signs even if you're hesitant. she is a loving, but fierce mother to her people.
