If they went away, I'm sure he'd find something else. Men give him plenty of fertile ground.
As Jesus said,
"That which cometh out of the man, that defileth the man.
For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders,
Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness:
All these evil things come from within, and defile the man."
