“There is always a rush of sadness and adrenaline in me as I take the life of a chicken” sounds like you’re not really comfortable with what your doing but you get an emotional payoff from it. I hope you recognize that you don’t HAVE to kill chickens at all and that there is a difference between wild animals killing for survival, the accidental deaths from growing crops, and the intentional breeding and killing of livestock animals. I have lived on a farm and took agricultural science in school, and have come to the conclusion that animal agriculture only wastes resources and adds unneeded suffering.
I also take issue with the title of the article. This is the Vegan Society’s definition of veganism: “Veganism is a way of living which seeks to exclude, as far as is possible and practicable, all forms of exploitation and cruelty to animals for food, clothing or any other purpose.” A vegan simply believes that less unnecessary suffering is better than more unnecessary suffering.
