For that matter, it is vegetarianism that has always been associated with cruelty and evil. Cain arrogantly refused to herd animals, and by restricting himself to agriculture of vegetables, imbued himself with a crude materialism that eventually induced him to murder his shepherd brother (explained in the Midrash Agadah and Bereishis Rabba). The ancient Egyptians hated the early Jews because the Jews were eating meat, especially of the animals worshipped by the Eygptians (Onkelos on Bereishis 43:32). And modern Hindus and Buddhists, likewise, practice partial or total vegetarianism as a result of their idolatry and materialistic crudeness. These are precisely the anti-Semitic and anti-G-d attitudes the evil nation of Amalek wishes to incite in people today, using vegetarianism as one important tool in promoting occult practices.
