He was an animal. Everyone knows never to corner one that's injured...even if it is just his pride.

The merely conscious being does not have a preference for continued life. Perhaps while having a pleasurable experience it has a preference for that experience to continue, or while having a painful experience it has a preference for that experience to end, but it will not have any preferences for the long-term future, and the desires it has do not survive periods of sleep or temporary unconsciousness, because unlike a self-aware being, it has no conception of its own future existence after a period of sleep. Thus if we are concerned only about the thwarting of preferences, for a merely conscious being, painless killing and administering an anesthetic seem to be equivalent. Killing does not thwart any more desires than putting the being to sleep. The being will be able to continue to satisfy its preferences after it awakes, but from the being's subjective perspective it is as if a new being, with new preferences, came into existence.

Everything that God sends us is beautiful, even though we may not understand it - and we only need to give it some proper thought to see that what God gives is just sheer happiness; the suffering is what we add to it.

I swore that I would not suffer from the world's grief and the world's stupidity and cruelty and injustice and I made my heart as hard in endurance as the nether millstone and my mind as a polished surface of steel. I no longer suffered, but enjoyment had passed away from me.

Let me implore the reader to try to believe, if only for a moment, that God, who made these deserving people, may really be right when He thinks that their modest prosperity and the happiness of their children are not enough to make them blessed: that all this must fall from them in the end, and if they have not learned to know Him they will be wretched. And therefore He troubles them, warning them in advance of an insufficiency that one day they will have to discover. The life to themselves and their families stands between them and the recognition of their need; He makes that life less sweet to them.If God were proud He would hardly have us on such terms: but He is not proud, He stoops to conquer, He will have us even though we have shown that we prefer everything else to Him, and come to Him because there is 'nothing better' now to be had.

When life gives you pain, accept it. When life gives you happiness, reject it.
