There is a difference between deserved justice and cruelty. You suggest cruelty.
They should be offered the same final meal they offered their victims before they murdered them.

I read somewhere that Texas has done away with the whole last meal deal because some guy in the legislature got tired of these guys ordering all sorts of crap and not eating it. Now if the soon-to-be-dearly departed is feeling peckish then they get what the general population is getting. There's no fun in reading what the swill-du-jour is.
