How does our inactions contribute to Karma?... For eg:How can you justify act of your cook killing an animal for your non buddhist guest?

I came to know His Holiness Dalai Lama serves his guests meat at his residency.... Is it dharma to ask your cook to kill an animal to serve your guest or further is it not your dharma to ask your cook to not kill an animal?.. So as to avoid confusion.. My main question is how will inactions contribute to our karma as much as our actions?.. Like here for eg. Our inaction of not stopping an animal being killed...
