Why was karma important

At the part after you have alerted the whole village, you have to run back.

While you are running, plant the animal traps down. Try to put them near places of cover, as that gives you a high chance of a enemy stepping on them.

The traps are not able to hurt you. Just don't get distracted when placing them.

Go to your Options and find "Look Inversion," then set it to "disabled."
