Joy. Mercy unfortunately makes me think of someone pleading for mercy during torture or something
Yes, ever since I read Michel Faber's (remarkably nasty) novel Under the Skin, 'Mercy' has given me the shivers. I agree that Clemency is nice, if it's the meaning that appeals.
I don't care for Joy, though -- I think it's too close to Joyce for me, and that feels dated. Plus the only Joy I've known well was a prurient gossip with eyebrows plucked into semi-circles that made her look perpetually astonished.
