The concern isn't about trading monkey lives for human lives, but instead that the component of needless torture and suffering is okay if it aids progress regardless of the effecacy of the outcome. I don't think people have as huge of a problem with monkeys being tested and dying in their trials more than they do about the lack of humanity and care about their position to the point of being dismissive.

yeah, I'd always trade monkey lives for human lives, but I'd also like the lives I trade to have been considered viable and worthwhile decisions to make from an ethical approach instead of being another number correlating to a large amount of attempts done. Saying similar to "I don't care if we kill 1000x more if anything at all improves" shows more of a lack of care to monkeys (i.e. their lives are being considered meaningless) than it does to defend the stance that killing more would be necessary to improve human lives.
