Slavery in ancient Rome played an important role in society and the economy. Besides manual labor, slaves performed many domestic services, and might be employed at highly skilled jobs and professions. Accountants and physicians were often slaves. Slaves of Greek origin in particular might be highly educated. The feeling of serving others is not the best.
The Koran forbids bacon or pork.
It also forbids tattoos, smoking, drinking etc.
