Time now for losing friends of the Gen 9:3 Permission-Gospel, of which yes we do have permission within this finite segment of the timeline, but, no, it's still not ideal according to the original design. While it's permissible, is it truly beneficial?
And doctors/vets that end their patients lives rather than discover new ways to treat the actual problem should not be considered healers as they might as well be replaced by some dude with a kinetic impact device or whatever if they don't bother healing but only "mercifully" ending "suffering". Fix the problem, not remove the patient. -_-
