If you want to kill these creatures because they linger around your base, be equipped with a sword and a simple pistol. You shoot them from afar and if they get too close, grab your sword immediately! If you want to tame them, either make a field of large bear traps, or shoot them from above if it's safe (stand on a object where they can't reach you or damage the object). In either cases you need to tranq them out, so don't even think of using a wooden club. Maybe you'll find a gap in a cliff and lure them into it. They fall from the cliff and you can tranq them out, but it won't be easy tho. There are enough trees and rocks they'll accidentally hide behind while trying to attack you. Also if they get too far, aiming with a crossbow will be hard.
