Do you believe it’s possible for non-Christians or those who don’t hold Scripture as a sacred text to believe in the sanctity of human life? Why or why not?

Yes, it is possible.

Explanation:

Because they are first, humans before they are Christians or non-Christians as the case may be. So the sanctity of human life is a moral intuition hence as long as a person can understand the difference between right and wrong, he or she can relate to the matter. Nonetheless, the degree to such belief for non-Christians can be graded low considering they lack the ingrained deposit of love and compassion which is perceived as a spiritual trait. And this is a question of the extent of belief in the sanctity of human life.

themselves

an intensive pronoun is a pronoun that ends in self or selves, such as himself, herself, themselves, yourself, ourselves. since band members is a third person plural, the correct intensive pronoun would be themselves. if the band was talked about as a collective noun, itself would be the appropriate intensive pronoun. intensive pronouns are used to add emphasis to the noun it's modifying which is why it directly follows it.
