I dare you then, to take a "Tame" burm, and place a small family pet in front of it. Go on. See what happens. You tell me that snake is "Tame" When its hungry, and very easily able to overpower and swallow that animal.
You can train a dog not to attack, and you can even train a cat to ignore pet rodents. You cannot train a pet snake, to ignore an easy meal.
They are NEVER "Tame" They are not like cats and dogs....
