Why are some people afraid to kill chickens? Do they feel cruel?

Maybe! But I prefer another timid one. I dare to kill chickens, ducks, fish and rabbits myself. I think it's no big deal. If I want to eat chicken, the chicken must die, so I will kill it. I can't understand why others are so afraid of killing chickens. They just haven't experienced the killing process, but they are all involved.

There is also a more artificial, deliberately showing their weakness, afraid to kill chickens ... I am really speechless for such people. Don't they feel cruel when they eat?
