>so did he kill any animal at all?
He likely slaughtered a few Passover lambs in his time.
>I thought your bible said do not kill?
You are mistaken. The commandment prohibits murder.
>You can argue about not eating any animal.
Both Paul and Peter addressed this. Paul said it was best not to cause anyone to stumble over dietary traditions. Peter related a vision and the instruction to 'slaughter and eat'.
