I could've killed him

I Could have ended it all today. I had a chance to take the kings life and get my revenge. But as I moved into position to kill him, something hit me. See, the king was praying to God and asking forgiveness while I was taking position to kill him. Oh I could've done the deed right then and there! But no, if the king was praying then God, being the merciful god he is, probably forgave him of his sins. Therefore, if I took his life then the piece of crap human being would go to heaven. I can't have that. Simple death is so much better then he deserves. I am going to wait until the moment when he is so deep in whatever sin he may decide to commit, that there is no chance of him going to heaven. I simply won't be able to truly feel good about myself and rest unless that SOB is burning in hell.
