Given that that most people would agree with 1 and 2 that:
1. Causing great suffering is wickedness if done in the absence of qualifying conditions.
For example bombing a city is generally wrong since it causes suffering but if bombing that city ends a war then that is a qualifying condition which may absolve the wrongness of that act.
2. Eating animals causes great suffering.
How can meat eaters see themselves as anything other than wicked people?
Certainly eating meat causes great suffering so the only thing that would keep it from being wicked would be the presence of a qualifying condition.
What is the qualifying condition in the case of meat eating? That is tastes SO YUMMY?
