Refrain from all intoxicants. Well, as Christians in the west, Thais seem to bend the rules on some occasions. Let's break it down. Although most Thais try not to deliberately take life, they all love to eat. Most of the Thai cuisine includes pieces of meat, usually pork, chicken or fish.
Monks also eat meat.
Eating meat requires the killing of animals. Well, monks excuse themselves by saying that they eat whatever falls into their bowl with neither enjoyment, nor disgust. Most slaughter men in Thailand are however non-Buddhists. Stealing Most Thais don't steal. But some do.
