For renouncers, the vinaya rules state clearly that one must not kill living grass, how much less so sentient beings! (In the vinaya it says: 'Once there was a monk who was robbed by bandits, and all his robes and belongings were taken. Knowing that the Buddha's disciples cherish living grass and uphold the precept not to kill it, the bandits feared he would pursue them later, so they tied the monk to the grass. That monk did not dare move for the entire day. Later he met someone who released him and he left.' If this is so even for living grass, how much more so for sentient beings?)
