One Helluva Servant (Helluva Boss x OC's)

A sinner..... what is it that makes a person a sinner? Killing, torturing the living, serving a false God, deceiver, corrupter, violence, gluttony, greed, lust, envy, wrath and out of all the sins I did was suicide I was lost for eternity just trying to survive in the afterlife finding my next purpose wishing I regret...
