Rhetorical question...of course.
Perhaps then you also intended as a rhetorical question your original statement that, according to Christian beliefs, it's interfering with God's will to provide lifesaving procedures for injury victims.

If you're sincerely interested in learning how Judeo-Christian believers view this, I'm sure there are several on this thread who can provide reading recommendations.
