Yeah when I read this I knew how you got your finger. Pointing your fingers toward the target is a bit dangerous(if you space your fingers too much, as you did) and it also adds a bit of unwanted torque on your bow, because when you shoot, unconciously you have to "catch" your bow, or it will fall out of your hands. Instead of pointing your fingers out, which is actually tensing up, allow your fingers to bend and slightly touch the center of your riser, keeping your fingers relaxed. No finger cuts, less torque, better shooting.
