[quote=@Animus]I'm not telling you to snatch people off the streets or anything of the sort. Rather, experiment on people whose lives are otherwise shit anyway. Take someone from a third world country, offer them prospects of food, lodging, money and the chance to make a difference in the world. You'll see very little people rejecting it. These are the people who are dying from hunger and suffering from fatal diseases/ailments that can easily be treated.

And what I'm saying is, take that person from a third world country, offer them food, lodging, and money, and treat the fatal diseases/ailments that can easily be treated, and heck, give them all the money you would've spent on experimentation, too, why not, for the sake of conversation. Then see what sort of difference they make in the world. These are not animals we're talking about -- their lives are every bit as important as the people you're trying to cure. 

I know it's not intentional, but your premise is inhumane from the very first. "You let them take the experiment, they get the hope of living." [i]In what way[/i] is that a reasonable bargaining position? Really sit back and think about it. That's monstrous.
