Why I am not a vegan

[Aion]

I'm not yet sure if free will means that an entity is able to have its desires met or that free will means that an entity is able to choose how to respond to experience. Perhaps some combination of the two. Does free will automatically mean an entity should have its desires met, whether these are instinctual or of higher intellect? Or is free will more a matter of the ability for an entity to choose from the moment it's actions, feelings and thoughts? What is that ability to choose, exactly? To have preference?

I realized in assessing the many approaches in this conversation that it often comes back to the idea of free will, however I am not sure there is actually a consensus on what free will is or what the idea of it implies.

I am looking for the connection between free will, choice and impulse. Is free will only a conscious activity or is it also unconscious activity? At what point does the free will of one entity 'cross' that of another? What exactly is the manifestation of this apparent reality or is it just a philosophical idea of 'freedom' that has been shaped from a particular ideology? I wonder where the idea of free will first came from, perhaps the topic of the angel and the 'fall'? Will have to do more research before I draw any conclusions.

Note, I am not polarizing this thought either way in the discussion in terms of what is right or wrong or STS or STO, just pondering on the mechanics and nature of free will itself.
