I believe that ALL living things have a soul. Does that mean every soul can feel pain or feel emotion, no. Does it mean they are any less of a soul, no. But it does mean that we should strive to respect all living things and treat them with care.

You believe what you want to believe, but I will always believe what I want to believe. This is what I believe....

Snakes have souls
Snakes do not feel or display emotions
Snakes TOLERATE handling. They do not seek it out.
Snakes can get used to a specific person but that does not mean they actually like or love that person.
Snakes are to be treated with care and respect

And that is really all I have to say in the matter without going deep into my spiritual and religious beliefs.
Couldn't have said it better myself.
