The Hero Returns - Vol. 1 Ch. 9

Remember kids. Kill your enemies. Because the mc was fool enough to avoid having a single humans blood on his hands, that one bad human is now going to try to genocide the whole village so now he will have several humans blood on his hands. A little blood now may save gallons in the future. For those reasons dude should've killed the old man just like he did the snake.

At the very least, capture & restrain the VC, let the village judge him. Don't just leave him free to do whatever
