One of the parts of developing new medicines is testing trials. It can sometimes be difficult to find people to partake in the trials or the trials may be too dangerous for open public testing.
I say we use pedophiles for these trials. To be more fair we only use the ones that committed especially heinous acts and are not likely to be reformed. This would not be against their will either, we can set up a system where they get some sort of reward in prison for participating such as payment or special privileges.
This would allow some of the morally questionable experiments to be performed without worrying about harming any innocent people.
