I would need a literary synonym of toy, but which would also have the nuance of object of malignant joy. I would like to use it in the context of someone becoming the toy (?) of some evil powers because of lack of strength of character.
I considered plaything and toy, but they are too modern, and besides, they do not have the intrinsic nuance of malignant joy.
I also considered laughingstock and derision which, although literary and even slightly antiquated, are too abstract. I also considered scorn which I like very much, but still lacks the nuance of the man's inability to defend himself. I wish to express that these forces play with such a person, as a cat plays with its prey before devouring it. Is there such a word in English?
He gave himself over to riotous living and became the __________ of demons.
I wouldn't mind an archaic word, but it needs to be still understandable today.
