Rather than get_role(), which returns the WP_Role object, if you're really only interested in knowing whether a role exists (for example, if you want to determine whether to remove_role() or something), how about wp_roles()->is_role( 'role-name' ); ? Maybe a tiny bit more efficient than get_role() and a bit more future-proof than digging directly into the global $wp_roles.

Why do not use the simple built in wp function get_role that returns a WP_Role object on success, null on failure ?
