I support the phoenix wright roleplay, but I think you'd find more success in just saying something like "this is kind of a glib analogy when the outcome is still genocide, don't you think?", or something along those lines, rather than asking like, a series of questions asking whether or not they find genocide to be an acceptable outcome. One of those will come off as bad faith, and put the defendant on the back foot, the other will get them to open up and possibly admit fault, or potentially come off much poorer to a jury, were they still to choose to object.
