I Eat Tomatoes
Just remember the others in the group aren’t innocent they wanted to kill the mc group but couldn’t cause the young master was there. Also the young master wanted to kill the mc group with the Indians to steal a kill. So everyone in that group are scum so no need to feel bad as less people will die when they are gone since they won’t be able to kill fighters for kills anymore. Also this world hasn’t different morals and environment so don’t push killing is wrong here cause if you let any live they will just kill again since they can get away with it in this world.
I can't like the MC for doing this. He put a few powerful innocent strangers lives in danger and made an enemy out of them unnecessarily. And judging by how these novels usually go, they will found out who did it and want revenge. Found the plot of the next arc! In terms of morality MC is officially worse than the villains.
