I'm sure that lives of those animals whom are being tortured for this tech to be developed were changed as well.
As you typed these words, millions of animals out in the wild were being devoured alive by other animals. Torture was here before humans.
Given the billions of animals we torture for food, at least the ones tortured for the good of humanity are slightly less unjustified. However, "animals kill each other in nature all the time" is not a good argument, because I don't have to hold myself to the moral standards of a hyena.
The hyena can't and won't appreciate it. Why do you have moral standards that don't require reciprocity? Do you think god will reward you in heaven?
