Would You Be Willing to Kill All the Puppy in Exchange for a Cure for Cancer?

Would you be willing to put several thousand sort of charismatic, fauna species extinct in exchange for a cure for cancer as long as it meant humans could still live? Would your answer change? Like before and after the trip, like we are more hesitant to not destroy Antarctica before you've gone. But once you involve puppies, I'm going to become much more hesitant is what's going on here. Is Mr. Chompers in a shot at the moment? He's returning to the house very shortly.
