Whatever food you eat is largely cultural, and depends on how you are raised. As an African, our forefathers are mainly hunters and farmers. They made large impression on their village (not only on their family) by coming home with their kill. Then the whole village could feast.
The only support I have for not killing animals for food is that all forms of killings are cruel, and all have respective right to live until they die a natural death, Same reason I don’t support capital punishment.
However, research has indicated that those who don’t have a form of animal protein in their diet are less healthy than those who do and thereby shorten their lives.
Spiritually, animals are made to be part of the human diet, and some are bred specifically for food, even as far back as early creation. Remember Cain & Abel. Jesus, a Jew also ate the Passover lamb.
