A snake has such a small head, I wonder about its brain

I do believe snakes can become tame to a certain degree, because when looking up tame snakes do fit into some of the listed definitions and adjectives listed.

As Vypyrz said most likely they register things as a threat or no threat. Food or no food. Their minds are simple and their learned behaviors are minute if any at all.
Most all is instinct. And they have triggers as far as when to go off that instinct,

Just like a pitbull, snakes can be tamed to a certain level but in certain situations they can snap just like that. Because beyond our efforts to "domesticate" and rid them of their instincts...the instincts will always be there harboring and chances are at some point something will trigger them.

Pitbulls are no more dangerous than a Rottweiller if bred and raised properly. The human race has made the pitbull into what is is today. I won't go into that here, but a snake and a pitbull comparison isn't a fair comparison.

Many have to realize that snake uses it's mouth for everything that other animals have other appendages to use. So instead of pushing you away with an arm, or a leg, they strike out at you. When they're hungry, they don't grab their food with a hand, they grab it with their mouths. Everything revolves around their mouth. So many can take this as agressiveness.

Just one man's opinion.
