Humans eat humans. To honour, remember and respect the dead, not just survival. If that's evil in your book so be it. Evil to me is cultural genocide and driving to suicide those who did what they needed to. Both can be depicted in fiction of course.
Ahem. Let me put it this way. I call any creature a monster who:
1. Goes about purposely killing people for fun.
2. Purposely tortures people for fun.
3. Enjoys raiding villages and towns with the sole intent of killing and eating people.
4. Enslaves people and cruelly mistreats said slaves, often eating them when they no longer prove useful or just because they're hungry or just for fun.
Goblins, trolls, orcs, hobgoblins, ogres, etc. Are considered "monster" races because they did these things. So, ever since the dawn of D&D, they were bad guys and evil. Now, in our modern culture, suddenly people want to turn them into alien races from Star Wars. There are no good or evil races.
Look. If in a D&D game, I ran into a human tribe full of people who did all the above things, I'd consider the whole tribe a monster tribe. If one of their kids was about to sound an alarm that would get me and my companions killed, I'd shoot that kid to prevent the alarm from being sounded. Would I like it? No. But I'd do it because if I didn't the greater good could be compromised.
Likewise, if I encountered a good tribe of goblins who didn't kill and eat people, I wouldn't view them as monsters. My point in BG3 is that the goblins are all monsters in the game. Those kids are literally going to eat poor Brian the dwarf who is cooking on a spit out front, and I'm sure Halsin is next. They're just throwing rocks at him to tenderize the meat. Larian is portraying the entire goblin tribe as evil. In fact, I'd venture to say that the only maybe not evil one is maybe the cook with Volo... maybe... But not likely because she's a cook who has likely helped dice up members of Aradin's crew and people from Waukeen's Rest to serve as main menu items for the entire clan, kids included.
And frankly, we should be careful about discussing all the cultural genocide stuff. We're talking fantasy here. If an alien race descended on Earth to enslave us and use us as cattle, harvesting our kids and such as food, I'm fairly certain we'd all be thinking about cultural and racial genocide. In d&d, that is literally what most goblins have done throughout the history of Forgotten Realms. They harvest people for slavery and food.
