Given the JW mindset of blindly following the GB's (aka "god's") orders and that they have been indoctrinated for years to believe that these people dying would be a good thing then I do believe that some would. I doubt they would admit it though.
I remember being at my mothers a couple of years ago when some disaster (earthquake?) was on TV and tens of thousands may have been killed. My mother started whittling on about "oh, I hope the poor brothers are ok" and I couldn't help but highlight her unchristian closed-minded thinking:
"Don't you mean you hope everyone is ok? Oh I forgot, Jehovah is going to kill all them anyway so what do they matter ... right?"
