You . . . don't understand. You have not seen. The faces filled with fear. Knowing that they're the last of their kind. Many seek to end their lives prematurely, but we will not allow it. To see the living suffer the Long Death . . . you have not experienced the thrill one gets knowing that they work for the benefit of our glorious race before they transpire. The slooooow suffocation . . . to exploit a sapient being for everything they are worth. It gives us strength. We are the masters of Death. And so it is that which we seek over all things living.Honestly any of them except neutering, I can't imagine Fanatical Purifiers being patient enough to wait for a pop to die of old age.
