I would not assume that he is weak, and you spelt "prey" wrong... but even if he is, then he will need to make a choice about his own participation in terms of whether it is good for himself or not.
No, no! I spelled it right. Like a priest praying for weak children to come into his lap, or Demon. U'r pick. You know, like wishing for the weak to come to you so you can satisfy your domination needs. And not 'prey', WTF!? are we jaguars in the jungle to savage our inner animal needs??
