Is it fair to say trolls, even the ones on the bottom of the hemospectrum, can withstand more pain than humans? You have the example of Terezi, who was alive for quite awhile despite being stabbed so much, versus Rose who was stabbed once

Condy died from a single stab through the chest, and Sollux beared the burning out of his psionics for as long as it took him to get to the Green Sun, so again, seems to be a case by case and wound by wound basis.
