“ Who other creatures' flesh consumes to feed his own?
How can he be possessed of kindness, who to increase his own flesh, eats the flesh of other creatures.
Kural-252
No use of wealth have they who guard not their estate;
No use of grace have they with flesh who hunger sate.
As those possess no property who do not take care of it, so those possess no kindness who feed on flesh. ”

“ Who eats of savoury meat, no joy in good can find.
Like the (murderous) mind of him who carries a weapon (in his hand) , the mind of him who feasts with pleasure on the body of another (creature) , has no regard for goodness. ”
