That post is not attempting to justify it. It’s explaining the reason. There’s a difference.
Torturing a person to death is wrong. But if a person is a victim of rape and domestic violence over a period of time by someone and they end up torturing and killing that person, I think most people understand why they did it.
Also, why did you post this? Are you trying to justify the actions that have been going on for almost a year now? Do you think it’s OK to kill 30,000 civilians and torture millions more in response to 700 civilians being killed?
