I would never write that, nor would I want to read it. That shit happened in one drama show I was watching, so many people were killed off suddenly and I'm like naaaah, fuck that. That's terrible, even if it's directly related to the main character's choices.
More tragedy than cruelty. Imagine in the real world... war or disaster generally demands painful sacrifices.
If every conflict, war, and disaster could be resolved through peaceful dialogue, there would be no need for the military. However, that reality is sometimes harsh.
