user5315: What is the difference between greed and karma?
For instance, a person eats meat greedily, greed for meat but no direct killing. Another person kills a cat (not for food) but he is not greedy. Which one is more unwholesome or causing more suffering, killing or greed?

user111: Greed is one of the 3 defilements that causes bad Karma. The other 2 are aversion and ignorance. A greedy thought is bad Karma.
Killing is caused by aversion. It is more unwholesome and causes more suffering compared to craving for the taste of meat. Because killing breaks the first precept.
