It's an interesting point. Giving chimps HIV is pretty sick, but if it means saving human lives then to my mind it's a necessary evil. If you know anyone who's life has been saved by a drug that was tested on animals it's pretty clear cut.
I actually agree with Keith, if we start torturing people then we lose the moral high ground and it's a slippery slope. Also a lot of massive mistakes get made in justice systems. That's the main reason I'm against the death penalty, quite a lot of innocent people have been executed.
Lock 'em up for life, it costs less than execution and at least that way if it turns out that they were actually innocent 20 years later they can be freed.
It's a hell of a can of worms to open...
