As per the law of karma, that which is your meat today, this dear beloved animal will make mincemeat of you tomorrow. In another birth.
Killing or eating animals is an act of beasts. Stirs within the devil. Sorry. It spurs evil. Thus is truth - at least the metaphysical.
You can only give happiness, if you have a stack of happiness in you.
No one dies pre-maturely. As is meant, happens naturally.
